ПЭТ/КТ В ОНКОЛОГИИ #ПРЯМОЙЭФИРБЛОХИНА

Our guest at the "Oncology Academy for Patients" is VIKTOR SOLOMYANNY, MD, PhD, radiologist, and head of the Radionuclide Diagnostics Department No. 2 at the N.N. Blokhin National Medical Research Center of Oncology, Ministry of Health of the Russian Federation. Contents: 00:00 Introduction 00:39 What is PET/CT and how does it differ from conventional CT and MRI? 02:16 Why is PET/CT usually prescribed? And at what stage? 03:13 Is PET/CT usually prescribed for any oncological disease? 05:03 PET/CT is currently perceived as a super-innovative, highly accurate imaging method. Is this true, or are there limitations to PET/CT? 08:19 Is there any preparation required before PET/CT? 10:22 If a patient takes medications regularly, say for diabetes or high blood pressure, should the dose be adjusted or discontinued before the scan? 12:09 Do patients sometimes develop allergies to radiopharmaceuticals? 14:52 Is PET/CT safe for the patient's health in terms of radiation exposure? How often can the scan be performed? 17:35 Does a patient remain "radioactive" after a PET/CT scan? 20:29 How is a radiopharmaceutical administered? Is it painful? 21:43 How long does the entire procedure take? 23:56 You said that while the patient waits for the radiopharmaceutical to attach to the cells, they should simply lie down or recline. And, as far as I know, you need to lie silently... 25:44 What if the patient is claustrophobic and is very afraid of being in the machine, in a confined space with extraneous sounds? 27:25 What about small children who have difficulty lying still for the entire duration of the examination? 28:08 And regarding the contrast agent, do you always administer it, or do you sometimes decide not to? What determines this decision? 30:20 Can I bring an accompanying person into the room where the machine is located? 31:24 Can I eat, drink, or drive immediately after the examination? 32:39 Do I need to wear special clothing for the examination, or how do I remove all my equipment before an MRI? 33:53 Can patients with a pacemaker undergo PET/CT? 35:04 Let's say a person has had the examination, goes home, and the results are displayed in their personal account. Who will interpret the report? 37:01 Can a PET/CT scan definitively determine whether a person has a benign or malignant tumor? 40:55 If a patient has recently had surgery, chemotherapy, or radiation therapy, can this somehow affect the PET/CT results and what the radiologist sees? 42:24 Can a PET/CT scan help detect a relapse at the earliest stage? 44:31 A viewer's question: Which organs or body parts are not visible during the scan? With HER2+ breast cancer, luminal B infiltrating ductal stage 2 (...) It's been 9 months, and I only have an ultrasound every 3 months. I'm worried about metastases. Is a PET/CT scan recommended? And when can it be done if 3 months have passed since radiation? 47:07 A viewer's question: One year of remission after breast cancer, grade 3 negative, stage 2. Does it make sense to have a PET/CT twice a year instead of all the individual tests twice a year (ultrasound, mammogram, CT scan of the internal organs and lungs, MRI of the brain)? 48:19 Viewer's question: Will a PET/CT scan detect metastases/hamartomas in the lung? 50:30 Viewer's question: Why does Ewing's sarcoma have a low fluorescence, like a benign tumor? But according to histology, it's a sarcoma. (I have Ewing's sarcoma in my nasal cavity.) Does it not like glucose? 51:58 Viewer's question: Can a PET/CT scan replace all the tests (MRI, CT, and bone scan) for annual monitoring after 5 years of remission? 52:50 Viewer's question: Can filgrastim injections be given if neutropenia is indicated the day before and on the day of the PET/CT procedure? What timing of the shift can be critical for PET/CT? Can early PET/CT (less than 3 weeks) yield false-positive results due to residual inflammation? 54:02 Viewer's question. Physiological accumulation of a radiopharmaceutical (RP) in the blood pool of the descending aorta (...) What does this mean? 55:27 Viewer's question. Diagnosis: C43.5. Second year of MTS. How often can PET/CT be performed, and can it be combined with a brain MRI with contrast? 56:48 Viewer's question. They haven't been able to make a diagnosis for five months; lymphoma or Castleman disease is suspected. Is this diagnostic method informative in this case? 58:01 Viewer's question. What premedication is given before PET/CT if there is high protein in the urine? 58:19 Viewer's question. What are the indications for PET/CT scanning for ovarian cancer? How informative is this method for this disease? 01:00:38 Viewer question: What drug should be used for PET/CT if there was a kidney tumor that was removed, but a new, unconfirmed tumor has appeared? 01:01:51 What new technologies and new research are currently being conducted in nuclear medicine? What awaits us in the near future? N.N. Blokhin National Medical Research Center Single Contact Cent...
