Procedure
  • You would be then directed to a room where a small dosage of 18 F – FDG / Sodium Fluoride will be injected in your vein.
  • After injection, you would be asked to quietly relax and rest in a separate room at our Centre for about an hour before you are taken up for the scan.
  • During this resting period, unless recommended by our staff, no attendants or relatives would be permitted to stay with you in this separate waiting room.
  • You are advised to stay calm, restrict physical movements and avoid talking to others while present in the room.
  • In case you feel any vomiting sensation or giddiness, inform the staff immediately by pressing the call bell.
  • You may be given oral contrast to drink. You will have to finish drinking it in around 30 minutes. This helps to get a better image quality. However, don’t force yourself to drink it in case you are feeling nauseatic.You would be required to drink plenty of water after the injection and till you are in the waiting room.
  • You will be asked to void (pass urine) before starting the scanning procedure. Take care to ensure that you don’t spill urine on any of your body parts.
  • You would be asked to lie down flat on your back on the bed of the PET-CT scanner and are expected to remain still during the entire scanning period of 15-20 minutes.
  • Your body would pass through a dough-nut like structure for obtaining the scan. Please let us know if you are claustrophobic or anxious.
  • You would be informed about the beginning and end of the scanning procedure by our staff.
  • After the completion of the scanning, you will be asked to sit in another room for some time. The Nueclear staff in the mean time will evaluate your PET-CT images and if needed may repeat your whole body scan.
  • Your PET-CT scan would be finally evaluated by our experienced Nuclear Medicine Physician.
PET and PET/CT scans are performed to
  • Detect cancer.
  • Determine whether a cancer has spread in the body.
  • Assess the effectiveness of a treatment plan, such as cancer therapy.
  • Determine if a cancer has returned after treatment.
  • Determine blood flow to the heart muscle.

RADIO IODINE THERAPY

PreRequisite Patient should not eat or drink after midnight on the day of the procedure. If you have been taking anti-thyroid medications, you must stop at least three days before the therapy is given. Frequently, the anti-thyroid medication is stopped for five to seven days before therapy. Radioactive Iodine I-131 (also called Radioiodine I-131) therapy is a treatment for an overactive thyroid, a condition called hyperthyroidism. Radioactive iodine I-131 may also be used to treat thyroid cancer. Low dose of iodine used for hyperthyroidism and high dose used for thyroid cancer patient required admission after high dose therapy.

    Gallium-68 OCTREOTIDE /DOTA/SOMATOSTATIN Scan

    Prerequisite No PreRequisite
    TIME REQUIRED Duration of the procedure 1-2hr
    TECHNIQUE DOTA studies are able to determine the extent of neuro endocrine tumor (NET)cancer and whether it has spread to the lymph nodes or other parts of the body, unlike traditional imaging technologies such as magnetic resonance imaging (MRI) and computed tomography (CT), which are often unable to detect the spread of NET cancer cells. Molecular imaging technologies help physicians select the most effective therapy for NET cancer, taking into account a tumor’s unique molecular properties and whether the cancer is localized or diffuse, or spread out.
    ProcedureThe study involves a special molecule called a monoclonal antibody developed in a laboratory and designed to bind to the somastatin receptors. This antibody is paired with a radioactive material called 68-Gallium that can be detected by a PET CT camera. When injected into the patient’s bloodstream, the radioactive antibody travels and attaches to cancer cells. The PET CT then produces three-dimensional images of the tumor and its location inside the body.
