☢️ Scintigrafie Ficat-Splină cu Sulf Coloidal (Liver-Spleen Scan)

Updated Liver/Spleen Scan 9/8/2024 ●Indications  To the assess size, shape, and position of the liver and spleen; detecting, measuring, and monitoring liver/spleen masses; differentiating hepatic hemangiomas and FNH from other liver lesions; evaluating hepatic function in acute or chronic liver disease; confirming patency of hepatic arterial perfusion catheters and evaluating pattern of blood flow via these catheters; identifying functioning splenic tissue and evaluating suspected functional asplenia. ●Radiopharmaceutical: Option 1 - 3-6 mCi Tc-99m sulfur colloid administered IV Option 2 - 20-25 mCi Tc-99m ultra-tagged RBCs administered IV ●Patient Preparation: No specific preparation prior to radionuclide administration. ●Conflicting Examinations/Medications: No Nuclear Medicine exams within the previous 24 hrs. No barium GI exams within the previous 48 hrs. ●Pregnancy/Lactation:  Pregnancy testing is only needed in potentially pregnant patients who state they could be pregnant. See Pregnant, Potentially Pregnant and Lactating Patients policy for specifics. Breast feeding mothers should discard breast milk for 4-24 hrs following Tc-99m sulfur colloid / RBC administration. ●Imaging Technique (for Sulfur Colloid scans): Collimator - LEHR or LEAP Photopeak - 140 keV 20% window for Tc-99m Image Preset Counts - 500k to 1 million counts/image Matrix Size - 256 x 256 Zoom - 1.23 Patient Positioning - supine ●Imaging Views (for Sulfur Colloid scans): Begin imaging 15-20 mins after radionuclide administration. Obtain anterior, posterior, RAO, LAO, RPO and right lateral images. Obtain an additional anterior image with a linear marker placed along the right inferior costal margin and xyphoid process. ●Imaging Technique (for Tagged RBC scans): Collimator - high resolution / LEAP collimator Photopeak - 140 keV 20% window for Tc-99m Image Preset Counts ◦Flow - 3 secs/image for 90 secs (30 images) ◦Fill-In - 60 secs/image for 24 mins (24 images) ◦SPECT - 64 stops, 25 secs/stop ◦Static - 100k counts/image Matrix Size - 128 x 128 (flow), 64 x 64 (fill-in), 128 x 128 (SPECT), 256 x 256 (static) Zoom - 1.23 Patient Positioning - supine ●Imaging Views (for Tagged RBC scans): Flow Images ◦Begin imaging immediately after radionuclide administration. ◦Obtain anterior and posterior images for 90 secs. Fill-In Images ◦Begin imaging immediately after flow imaging

◦Obtain anterior and posterior images for 24 mins. SPECT Images ◦Begin imaging immediately after fill-in imaging ◦Obtain SPECT images of the liver and spleen with axial, coronal and sagittal reconstructions. ◦Obtain a 3D horizontal spinner. Static Images ◦Begin imaging immediately after SPECT imaging ◦Obtain anterior and right lateral images. ◦Check with the Radiologist to determinate if any other imaging plane or more delayed images are needed.
