First Time in Bangladesh

128 Slice PET-CT Scan

PET-CT (Positron Emission Tomography-Computed Tomography):- a highly advanced “Leading-Edge” technology, that can save lives by diagnosis, staging and monitoring cancer as well as other diseases.

In the pursuit for excellence, we have the latest ultrafast 128 Slice multi detector high resolution PET-CT Scan, capable of performing very fast and high resolution whole body PET-CT scanning with highly optimal image quality in all planes in a single scan at 0.35 second.

PET-CT allows physicians to pinpoint the location of cancer within the body

Advantages of PET-CT

Unlike CT or MRI, which provides anatomical details, PET-CT provides functional changes related to physiological and chemical metabolic processes in addition to structural detail. This is very important since functional change predates structural changes in tissues by long durations and thus PET study demonstrates pathological changes long before they would be revealed by structural imaging modalities like CT or MRI. PET study demonstrates more about the cellular level metabolic status of a disease than other types of imaging modalities.


PET-CT scan can be used for detecting ailments in the following categories:

a. Oncology

b. Neurology and Psychiatry

c. Cardiology

d. Infection and Inflammation

e. Pediatrics

f. Dental

What is PET-CT?

Positron Emission Tomography (PET) and Computerized Tomography (CT) are both standard imaging tools that allow physicians to pinpoint the location of cancer within the body before making treatment recommendations. The highly sensitive PET scan detects the metabolic signal of actively growing cancer cells in the body and the CT scan provides a detailed picture of the internal anatomy that reveals the location, size and shape of abnormal cancerous growths.In a hybrid exam, we perform PET and CT scans during a single session. When the resulting scans are combined, they form a single image showing metabolic activity in relation to your body’s anatomy. This allows the physician to pinpoint the location of cancer within the body before making treatment recommendations.

PET/CT exams are minimally-invasive, and in many cases, they can reduce the need for further tests or more invasive procedures.


Because PET and CT technology each have some medical limitations, we perform hybrid exams, eliminating the need for separate scans. The images produces by these exams let your radiologist and referring physician view the way your body’s structures look and behave. The CT images show physical landmarks to precisely locate the PET scan’s findings. For example, PET scan can show cells that may be cancerous, while CT scan can show precisely where those cells are located in your body. Doctors use PET-CT scans to make better diagnoses and to determine the best course of treatment for a range of diseases and disorders in several practice areas, including oncology, cardiology and neurology.

While a CT scan provides anatomical detail e.g. size and location of the tumor, mass, etc., a PET scan provides metabolic detail that is cellular activity of the tumor, mass, etc. Combined PET-CT is more accurate than PET and CT alone.

Anatomical: CT Scanners send x-rays through the body, which are then measured by detectors in the CT scanner. A computer algorithm then processes those measurements to produce pictures of the body’s internal structures.

Metabolic: PET images begin with an injection of 18F FDG, an analog of glucose that is tagged to the radionuclide F18. Metabolically active organs or tumors consume sugar at high rates, and as the tagged sugar starts to decay, it emits positrons. These positrons then collide with electrons, giving off gamma rays, and a computer converts the gamma rays into images. These images indicate metabolic “hot spots,” often indicating rapidly growing tumors because cancerous cells generally consume more sugar/energy than other organs or tumors.

The entire examination usually takes less than 30 minutes, providing comprehensive diagnostic information to your health care team very quickly. The PET-CT system provides exceptional image quality and accuracy of diagnostic information.

The GE-LightSpeed® VCT-XT 128-Slice PET-CT Scanner

At Medinova Imaging, we recognize the many benefits that PET/CT technology offers patients and their doctors. That’s why we were the first imaging center in Bangladesh to introduce the GE’s most advanced GE-LightSpeed® VCT-XT 128-Slice PET-CT Scanner in an outpatient setting.

The PET-CT system enables earlier disease detection, as well as more accurate diagnosis, which can lead to better treatment decisions. Access to such valuable information offers better outcomes for patients with cancer, cardiac defects, and neurological conditions, such as Alzheimer’s.

How do I prepare for my PET-CT?

  1. On the day prior to the scan you must be on a low carbohydrate, low sugar and no caffeine diet.
  2. You must be well hydrated. Drink plenty of water the day prior to the study and on the day of the scan.
  4. If appointment is in the afternoon, you may eat a regular breakfast 6 hours prior to the appointment time (dry toast, scrambled eggs, milk only) NO SUGAR and NO JUICES.
  5. You must take oral medications in A.M. with water only. Diabetics may take oral medications. NO INSULIN IN THE A.M.
  6. If you are diabetic, please inform our Imaging staff member when confirming your appointment. You may be asked to alter your medication intake.
  7. No strenuous exercise for 48 hours prior to the scan.
  8. You must bring most recent CT, MRI or other relevant films and reports on the day of the scan.
  9. Do not wear jewelry and no metal on your body or clothing.
  10. Try to dress in warm, comfortable clothing as scanner room is kept cool.
  11. You will be asked to remain still for up to 90 minutes. Please call if this is a problem.
  12. Please notify us within 24 hours of appointment time, if you are unable to keep appointment.
  13. Please arrive at least 30-40 minutes before your appointment time.

What Can I Expect During My Exam?

On the day of your scan, you will receive a small injection of a sugar with a low-dose radioisotope called Flourine-18 FDG. This substance will circulate throughout your body and will be metabolized by your cells and organs. During this process, you will be asked to relax for up to 90 minutes. You will be in a rest room with a relaxing chair couch. Your room and the exam room may be cool, so be sure to wear warm comfortable clothing.

Because diseased cells, such as cancer cells process sugars differently than other cells, the PET-CT system is able to measure this increased metabolic function. These findings show our radiologist that a problem may exist.

Once the sugar fully circulates through your body, you will be asked to lie down on the PET-CT scanner bed to begin your exam. Shortly after the exam begins the CT scanner will make some noise. DO not be alarmed, as these sounds are normal. Once the CT exam is complete, the PET scan will begin. Following this portion of the exam, images of your body’s metabolic activity will be combined with images from the CT scan to complete a detailed picture of your health.

PET-CT Technology is safe and Medinova Imaging follows all steps to maintain patient comfort during the exam. You can help assure the clarity of your scans by remaining as still as possible and by breathing normally while the system is scanning. Unless otherwise specified, you can resume your normal activities immediately following your exam. To eliminate the sugar from your body, it is important that you drink as much liquid as possible for the remainder of the day.

After analyzing and interpreting the images, our Imaging radiologist will write the findings and to deliver your report for your doctor. Remember, only your doctor can discuss the results of your exam with you.
