68Ga-DOTA positron emission tomography/computed tomography (PET/CT) is used to localize primary and metastatic tumours of neuroendocrine origin. Patients with known history also undergo this test to detect residual, recurrent or progressive disease (restaging) & determine somatostatin (SST) receptor status.
Test information: Fasting: 2-4 hours
Reporting: Within 2 hours*
- Fasting for 2 - 4 hours.
- Please carry all medical documents, including doctor referral, previous PET-CT reports with CD for comparison, report of any CT, MRI and blood reports etc.
- Please carry a Serum creatinine blood report.
- If you are allergic to contrast media, pregnant or breastfeeding, please inform staff before the test.
- Always try to reach 15 min before appointment time as the radiopharmaceutical (tracer) used for 68Ga-DOTA PET-CT has a short half-life, and any delay may cause tracer decay, and you may be rescheduled for another day.
- Please carry identification proof such as an Aadhar card, pan card etc.
- 2-4 घंटे का उपवास।
- कृपया डॉक्टर रेफरल, तुलना के लिए सीडी के साथ पिछली पीईटी-सीटी रिपोर्ट, किसी भी सीटी, एमआरआई और रक्त रिपोर्ट आदि सहित सभी चिकित्सा दस्तावेज साथ रखें।
- कृपया सीरम क्रिएटिनिन रक्त रिपोर्ट साथ रखें।
- यदि आपको कंट्रास्ट मीडिया, गर्भवती या स्तनपान से एलर्जी है, तो कृपया परीक्षण से पहले स्टाफ को सूचित करें।
- हमेशा अपॉइंटमेंट समय से 15 मिनट पहले पहुंचने का प्रयास करें क्योंकि इसमे उपयोग किए जाने वाले रेडियोफार्मास्युटिकल (ट्रेसर) का हाफ-लाइफ छोटा होता है और किसी भी देरी से ट्रेसर का क्षय होकर समाप्त हो सकता है और आपको अगले उपलब्ध स्लॉट पर पुनर्निर्धारित किया जा सकता है।
- कृपया आधार कार्ड, पैन कार्ड आदि जैसे पहचान प्रमाण साथ रखें।
- After registration and payment, the patient's medical history is taken, including checking referral, treatment and investigation records, history of last meal and any allergy to contrast media, pregnancy or breastfeeding status, etc., depending on the clinical requirement.
- The patient is given clothes to change if felt necessary.
- Height & weight is recorded. An intravenous cannula is fixed for the administration of tracer and contrast media.
- The patient is injected with radioactive material (68Ga-DOTA) and advised to relax for a duration to allow the tracer to be distributed within the body with an adequate target to background ratio.
- The patient is asked to pass urine before scanning. Scanning may take 15-30 minutes.
- Recorded images are verified and if delayed images are needed, the patient is advised accordingly.
- Once these sequences are over, the patient is free to go home. The procedure takes approximately 2–4 hours, depending upon several variables. In the case of delayed images, this time may increase.
