Q. What is TMT?

A. TMT (Tread Mill Test) is the recording of heart’s electrical activity while it is under the stress of increased physical demand. This is also known as exercise tolerance test or Cardiac Stress test. Chest, arms and legs are involved in TMT test. The TMT at Elbit Diagnostics assess the heart muscle’s response to the need for additional oxygen, which occurs during increased physical activity. The uses of TMT are:

  • To evaluate if complaints of chest pain are related to the heart
  • To determine if blockages exist in a coronary artery or arteries supplying the heart with oxygen-rich blood (coronary heart disease or CHD)
  • To identify an irregular heart rhythm that only occurs during activity
  • To monitor the heart’s response to cardiac treatment or a procedure to open a coronary artery
  • To determine a safe level of participation before the start of an exercise regimen
  • To plan the pace and intensity of rehabilitation after a heart attack
  • To screen for the presence of asymptomatic CHD in certain high risk people

Q. What is Renal Ultrasound? What are the parts of the body that are involved in it? What are the         instructions to be followed before the test?
A. The Renal Ultrasound test uses sound waves to study the renal system, which includes the kidneys, bladder and ureters.

The test involves kidneys, bladder, ureters, abdomen and back.

The patient should avoid carbonated drinks, such as sodas and seltzers before the test.
The patient must have a full bladder for the test, and should not empty his/her bladder until after the renal
ultrasound.

 Q.What is the procedure for X-Ray Imaging?
No anesthesia or any special intervention is required during the procedure. A lead shield is placed over you to protect your reproductive organs. You lie on your back underneath the X ray machine, and remain still while the X-ray is taken. You may be asked to shift to other positions for more X-rays. These X-rays may be taken with you standing up or lying down - the X-ray technician will help position you against the film (which looks like a large board) so that the clearest pictures may be obtained. Usually pictures from both a front view and a side view are taken.

For cervical spine x -rays (neck X-rays), you will be instructed at times to open your mouth as wide as you can. This is so that your teeth are moved out of the way in some pictures and don't block the view of the bones that are highest up in your spine. For chest X-rays, you will be asked to take in a deep breath just before each picture is taken.

The technician will leave the room or stand behind a screen while he or she controls the X-ray camera. Our technician requires no special intervention during the X-ray test. The image generated from X rays due to differential absorption by bones and tissues is taken on a cassette. You may resume all normal activity after the procedure.

The imaging procedure will not last for more than 10 minutes. However it will take the X-ray department between 20 and 40 minutes to develop the pictures from your X-ray. It will take additional time for a doctor to examine the X-ray and to decide how it looks. Typically you can get the results on the same day the X-ray was taken.

Te head CT Scan is an X-ray scan that utilizes a computer to produce cross-sectional images of the head and brain. A CT scan is done to study the skull, brain, jaw, sinuses and facial bones for signs of injuries, tumors or other disease.

The doctor may recommend a head CT if you have any of the following symptoms:
•  Headache
•  Seizures
•  Head Injury or injury to the face or eyes
•  Dizziness or problems with balance
•  Pain
•  Confusion
•  Behavior or personality change
•  Chronic nasal congestion
•  Cough
•  Swelling in the face, head or neck

Many conditions and diseases can be diagnosed with a head CT at Elbit. These include:

•  Brain tumor
•  Spread of cancer from another location (metastases)
•  Cysts
•  Congenital brain malformations
•  Bleeding
•  Strokes
•  Aneurysm
•  Swelling due to concussion or other trauma or due to infection
•  Sinus disease
•  Fractures of the skull, jaw or facial bones
•  Hydrocephalus (excessive accumulation of cerebrospinal fluid in the head)
•  Abscess
•  Chronic sinusitis

Q.What is Mammography? What are the do's and don'ts to be followed before a Mammography test?

The use of low-dose X-rays (radiation) to make a picture of the tissue inside the breast. The resulting picture is called a mammogram.

No diagnostic tests are necessary before a mammogram, although monthly self-exams and yearly exams by your regular practitioner are recommended. Schedule a mammogram when breast tissue is least tender, typically a week after your period. Some women report less discomfort if they avoid caffeinated beverages and take 400 IU of vitamin E per day for several weeks before the exam.

•  If you have breast implants, ask if the facility uses special techniques to accommodate implants, before    making an appointment; implants make it more difficult to see all the breast tissue.
•  Do not apply deodorant, talcum powder, lotion or perfume near your breasts or under your arms on the    day of your mammogram
•  Wear a two-piece outfit; you will need to remove all of your clothing and jewellery from the waist up and    change into a gown that opens in the front
•  Bring copies of precious mammograms and reports with you
•  Inform the technician if you are pregnant or have breast implants.
•  Describe any breast problems to the technician before X-rays are taken

The abdominal CT scan is an X-ray scan to produce the cross-sectional images of the abdomen. A serum creatinine test may be conducted before abdominal CT scan if our radiologist feels the need.

No Anesthesia is needed, however if a contrast dye is needed, it is either injected into a vein or you will drink it in the form of solution. You'll be positioned on a special movable table, called Gantry, partway inside the CT scanner, which is usually donut shaped.

The gantry advances you very slowly through the CT scanner. You'll need to be very still during the entire test. As the operator initiates the scan, the X-ray unit inside the scanner will rotate around your body emitting a fan shaped X-ray beam into your body. This penetrates into your body and is received by the detector and converted into electrical data. This data is processed into images that appear on the computer inside a separate console room, our expert radiologist/technicians in the console room are always alert to your safety concerns while the equipment is in operation.

Our technician may ask you to hold your breath at certain points, so that movement does not blur the picture. You are able to talk to our technician and/or doctor during the exam, so if you are in pain, frightened or concerned in any way, you can communicate this immediately to our technician who keep you in view at all the times.

A special speaker is used to deliver any instructions to you. When you receive an injection of contrast dye, you may feel flushed and you may notice a salty or metallic taste in your mouth. Some people experience brief nausea as the dye circulates. However all such symptoms are transient.

A Holter monitor is a test that allows your doctor to see whether there are changes in the heart's rhythm or electrical appearance over a longer period of time than can be easily observed during one doctor's test. The chest and the heart are involved in the test.

The complete test may be conducted for 24 hours or 48 hours for which the device shall be on your body. However the time at the center is around 15 minutes for attaching the equipment on your body and another 15 minutes after the results are to be collected. It may take a day or so before your recordings are printed and examined.

At Elbit we assure you of an accurate test analysis as long as you follow our instructions. Our technicians shall provide you with all the instructions, hook up procedures and recorder maintenance. The Holter test at Elbit provides you with the best digital recording and analysis techniques to locate minor rhythm changes in your heart difficult to examine by conventional techniques.

No Anesthesia is required during the test. You lie on a table and the doctor applies a sound conducting jelly to your abdomen over your bladder and kidneys. The ultrasound machine has a hand-held instrument called a transducer or a probe, which looks like a microphone or wand. The probe is passed over the skin where the jelly was applied, It sends sound waves into the body, which bounce off the internal organs and echo back to the transducer. The echoes are converted to images that are displayed on a screen. Our radiologist examines the images on the screen and may take a photograph for further assessment.

The "Logiq 7 Standard" ultrasound equipment from GE Medical Systems installed at Elbit has as many as 12 different probes to diagnose a variety of tissues. The scan image can be adjusted using the:

•  B mode (for 2D images for the anatomical structure of soft tissues)
•  M mode (to display tissue motion over time)
•  Colour flow mode (to add colour coded qualitative information in any modes)
•  Doppler mode (to provide velocity of moving tissues and fluids or to examine blood flow data selectively    from any region) and
•  3 D mode (to visualize 3 dimensional images)

Correct patient identification is done through a special Patient touch pane, which stores all your details. Special features on our equipment allow visualization of complex blood flows and tissues, image storage facilities and graphic tools for designing customized reports. At the end of this procedure the ultrasound image is examined for abnormal masses or blockages.

The entire procedure can take around 30-45 minutes.

To understand this first we need to understand "Osteoporosis". Osteoporosis is the condition of having weak or thin bones, which are more susceptible to fracture, even with minimal injury. Osteoporosis can result in vertebral fractures, which cause a stooping over of the spine. Osteoporosis can also increase the risk of hip fractures, a major problem for older people. Because there are now some treatments to help build up bones in patients who have osteoporosis, it is helpful to have a test that will show how weak a patients' bones. This test is the "bone density" test, also called "Bone Densitometry".

With the help of the information about bone density the Bone Densitometry test at Elbit helps us diagnose:
•  Low Bone Density/Bone Mass
•  Height Loss
•  Pulmonary dysfunction
•  Fractures (hip, vertebral, forearm etc)
•  Rheumatoid Arthritis
•  Malabsorbtion Syndrome
•  Premature menopause
•  Prolonged Amenorrhea
•  Hyper Parathyroidism
•  Kidney Failure
•  Liver disease

Q.What is the procedure for mammography?

No Anesthesia is required and all you need to do is to stand/sit in front of our special x-ray machine.

You stand in front of a special X-ray machine, which has a platform to place your breast on. Our technician adjusts the height of the platform, then lifts and positions one breast between a special cassette that holds the film and a compressor paddle that holds your breast. The paddle is brought close to the platform and the breast is compressed to hold it in place and allow for a clearer image. You can tell our technician if the plate compresses so tightly that it feels painful.

Two pictures of each breast are taken during a screening mammogram. During one, you face toward the platform and the image is taken looking down at the breast. For the second, you turn slightly to allow for an oblique view. These X-rays are repeated on the other breast. Extra images, from different angles, may be necessary if you have breast implants. You'll be asked to wait at the facility until the X-rays are developed, in case more images are needed.
