Rest thallium or the "Resting Myocardial perfusion imaging" is commonly performed to see the blood flow into the heart's muscles where the patient's physical or medical conditions do not allow for stress myocardial perfusion imaging or stress thallium. The term rests myocardial perfusion imaging is more appropriate to name as any institute hardly uses thallium-201 and most of the centres use 99mTc-MIBI because of better image quality, low radiation burden and ease of availability.
Test information: Fasting: 4-6 hours
Reporting: Within 2 hours*
- 4 to 6 hours of fasting is required on the test day.
- Please carry all medical documents, including doctor referral, previous reports such as Echo, ECG, Angiography, MPI etc.
- Please wear comfortable clothing, and male patients are advised to shave their chest.
- Please carry some oily food such as butter-cheese-sandwich, puri-sabzi, parantha-subzi etc. This helps clear the background near the myocardium and improves the image quality.
- This is a long procedure and may take about 4 - 6 hours to complete if performed in a one-day protocol. Some patients may choose a two-day protocol where stress or rest parts are performed on separate days.
- Please carry identification proof such as an Aadhar card, pan card etc.
- परीक्षा के दिन 4-6 घंटे के उपवास की आवश्यकता होती है।
- कृपया डॉक्टर रेफरल, पिछली रिपोर्ट जैसे इको, ईसीजी, एंजियोग्राफी, एमपीआई आदि सहित सभी चिकित्सा दस्तावेज साथ रखें।
- कृपया आरामदायक कपड़े पहनें और पुरुष रोगियों को सलाह दी जाती है कि वे अपनी छाती को शेव करें।
- कृपया कुछ तेलयुक्त भोजन जैसे बटर-चीज़-सैंडविच, पूरी-सब्जी, परांठा-सब्जी आदि साथ रखें। यह मायोकार्डियम के पास की पृष्ठभूमि को साफ करने में मदद करता है और छवि गुणवत्ता में सुधार करता है।
- यह एक लंबी प्रक्रिया है और अगर एक दिवसीय प्रोटोकॉल में किया जाता है तो इसे पूरा करने में लगभग 4 - 6 घंटे लग सकते हैं। कुछ मरीज़ दो-दिवसीय प्रोटोकॉल का चयन कर सकते हैं जहाँ तनाव या आराम के हिस्से दोनों अलग-अलग दिनों में किए जाते हैं।
- 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, etc. Informed consent is also obtained at the same time.
- An intravenous cannula is fixed, and injection medicine is prepared parallelly.
- A tracer with a small amount of radioactivity is administered into the veins. The radiopharmaceutical flows through the bloodstream, and part of it, deposits in the myocardium which can be imaged.
- The patient is asked to have some food.
- After about 40 minutes, the patient is taken for a scan under the gamma camera. The scan goes about 15-20 minutes.
- The images are verified, and if it is fine, the patient is asked to go home.
