The most advanced

PET/CT in India


Here at SRMS FIMC, we have got one of the most advanced fusion imaging modality in the form of Biograph mCT Flow PET-CT scanner which for the first time in this part of world, can provide us the most detailed information about any functional abnormality in the human body; basically in oncology but not limited to; with some diseases of neurology and cardiac origin as well.

About the PET-CT Scan

PET CT is a diagnostic imaging test primarily used for detection of cancer and several other ailments. The PET-CT Scan is a test that is done on a special PET-CT Machine which performs the 2 scans together:

PET Scan: The Positron Emission Tomography or PET Scan component marks most actively upataking cells in the body. During the test, a small dosage of a Radioactive Tracers is injected into the patient. This molecule is an isotope which is actively uptaken by most active cancer cells in the body. The uptake of the tracer is measured by the PET scan component of PET/CT scan, to highlight and mark most cancers.

CT Scan: The Computed Tomography or CT Scan is used for anatomical localisation of the body. A diagnostic quality CT Scan is performed along with the PET scan for the anatomical evaluation of the tests. Prior to the scan, all patients are given oral contrast (positive/negative) to drink. During the scan, intravenous contrast is injected (unless creatinine is high / history of prior allergy / referring physician’s discretion).

  • Do not eat or drink anything for 6 hours before the PET-CT scan on the day of the test. Only plain water (hot/cold) can be drunk.
    (No fruit Juice, Lemon water, Karha, Prasad, dahi-chini, tea, coffee, gur, chocolate, toffee is allowed with in 6hrs before the test otherwise you test may be cancelled)
  • Do not consume excess sugar/starch/alcohol one night before test. For best results, please abstain from smoking for atleast 3 days prior to your PET Scan test.
  • It is forbidden to do any kind of exercise / running / strenuous work before 24 hours, this may affect the results of the test (report).
  • On the day of the test, come wearing light comfortable clothes, if possible, do not wear jewelery because all these will have to be removed before the test.
  • Notify us if you have had or have had an allergic reaction (or to intravenous iodinated dye / oral dye) before the injection of any radioactive drug / before the scan begins.
  • If you feel afraid of enclosed spaces, then tell the doctor about it. (At the time of appointment)
  • If you have diabetes and on medicines to control diabetes, please inform us about your diabetic prescription for us to plan the needful for your test. Your fasting diabetes level under control to 160-170 mg/dl.
  • If you are or may be pregnant, be sure to tell our staff/doctor before injecting radioactive medicine for PET-CT test.
  • If you are breast-feeding a baby, in this test, a small amount of the radioactive chemical injected into the patient can be detected in the mother’s milk for some time after the test. If the mother has had a PET-CT, the baby should not be breastfed for 1 day after the scan. Patients should not bring young children and pregnant women with them.
  • Total stay time required in the department for PET-CT scan will be approx. 3-4 hours. Kindly bring your food snacks etc. that can be given to patient after the scan done.

Information about Scan Procedures

  • It is a painless test .
  • First the diabetes level is checked after that a cannula is placed in the vein of the patient’s arm.
  • Shortly before the PET-CT test, a type of radioactive chemical is injected, usually into the cannula in the arm vein.
  • It takes at least 1 hour for this chemical to spread throughout the body. During this, the doctor forbids the patient to move and speak. And sitting separately in a solitary room is asked to drink water and urinate.
  • During the examination, the patient can also be given an injection of dye into the vein for CT scan on the advice of the doctor.
  • It may take 15-20 minutes for the machine to complete the test.
  • Some patients require sedation as per their medical condition, if so they will be informed about that and they need to give an informed consent prior to that.
  • After the test, patients can take their food and all their medicines.
  • After reviewing the initial scan by the doctor of nuclear medicine and if needed, a delayed scan may be required in some cases, which will be taken after 1-2 hours and may take 5-10 minutes in scanning.

Information after the PET-CT scan

  1. You can go home and get back to your daily routine. You can take your food and all your medicines.
  2. Adequate amount of fluid / water has to be consumed and urine has to be passed out so that the remaining medicines in the body come out.
  3. If patients are admitted in a hospital, they can be admitted back to their ward.

Important information for PET-CT Scan

  • It is best to have a PET-CT scan at an interval of 4-6 weeks after Surgery/Radiotherapy/Chemotherapy.
  • A PET-CT scan in the middle of chemotherapy course can be done 2-3 days before the next chemotherapy cycle.
  • Give samples for blood/urine tests before PET CT scan or after 24 hours.

Using Flow Motion Technology to

Overcome Today’s PET/CT Challenges

Until now, PET examinations have been performed in sequential bed positions, alternating between acquisition and patient table motion. As such, image quality and quantitative accuracy have always been restricted, and scans often resulted in higher dose and greater patient anxiety. Powered by Siemens’ revolutionary FlowMotion technology, Biograph mCT Flow is the world’s first PET/CT system to eliminate the demand for stop-and-go imaging.



With Flow Motion examinations, parameters such as speed, image resolution and motion management can be easily adjusted to the precise dimensions of organs and routinely



FlowMotion technology eliminates overlapping bed acquisitions while maintaining uniform noise sensitivity across the entire scan range, enabling



FlowMotion allows easy anatomy-based scan planning where only the desired area is scanned.



Biograph mCT Flow is the first-and-only PET
