    Study Notes

    Special Radiological Procedures for Biliary and Reproductive Systems

    • Imaging Technique for Multiple Liver Scans: PET scan allows for multiple liver scans after a single contrast injection due to fast imaging times.
    • Most Sensitive Sequences for Hepatic Detection: Hepatic arterial phase and FSE T2-weighted sequences are the most sensitive for detecting hepatic abscesses.
    • Post-Operative T Tube Cholangiography Indication: One indication is to rule out biliary tract calculi.
    • Technique for Intra- and Extrahepatic Biliary Tree Demonstration: Heavily T2 sequence is used to demonstrate the intra- and extrahepatic biliary tree and pancreatic duct.
    • Fasting/Fluid Restriction in Liver Ultrasound: Fasting or fluid restriction in liver ultrasound is required when the gallbladder should also be examined.
    • CT Cholangiography Scan Timing: CT scan should be obtained immediately after infusion of the contrast agent.
    • Ultrasound of Gallbladder and Biliary Indications: Indications for ultrasound include stones, jaundice, fever of unknown origin, and right upper quadrant pain.
    • Hemangioma Enhancement Pattern in Liver CT: Hemangiomas typically show peripheral continuous enhancement in arterial phase liver CT.
    • Liver Metastases on T1-Weighted Images: Most liver metastases appear hyperintense on T1-weighted images.
    • Magnetic Resonance Imaging for Fatty Liver: T1-weighted GRE fat-suppressed volume acquisition sequences are commonly used.
    • Pancreatic Body Location: The pancreas body is located to the splenic vein in a transverse epigastric scan.
    • Intraoperative Cholangiography Equipment: Equipment includes an operating table with CR/DR available.
    • Pancreas Examination Costs and Implications: Various methods like MRI, MRCP, and CT, are used depending on the examination needed.
    • Percutaneous Transhepatic Cholangiography Complications: Biliary leaks and adverse reactions are potential complications during contrast injection.
    • Biliary Drainage Potential Complication: Guidewire placement above a stricture can cause blockage of catheters.
    • Magnetic Resonance Cholangiopancreatography (MRCP): This is a noninvasive procedure that uses heavily weighted T2 images to depict stones and obstruction in the biliary and pancreatic ducts.
    • Intraoperative Cholangiography: This procedure is performed before cholecystectomy and is performed before cholecystectomy.
    • Optimal CT Scan Slice Thickness for Pancreatic Imaging: Between 0.625 mm to 1.25 mm best for the pancreatic phase.
    • CT Imaging Phase for Liver: The single-phase contrast-enhanced computed tomography image correctly depicts the liver during the arterial phase.
    • Ultrasound Portal Vein Examination: The best approach is a transverse intercostal or epigastric.
    • Liver CT Indications: Suspected focal or diffuse liver lesions, staging of malignancy, and other abnormalities such as pain or masses.
    • Percutaneous Transhepatic Cholangiography Indications: One of the indications is to place a percutaneous biliary stent.
    • Imaging for Hepatocellular Carcinoma: The best combination of phases for imaging is early and late arterial, portal venous and delayed phases.
    • Contrast Medium for Cholangiography: Low osmolar contrast medium (LOCM) is preferred to avoid obscuring any calculi.
    • Imaging Plane for Pancreatic Head Tumors: Oblique coronal plane is the best plane for these types of tumors.
    • Causes of Air in Biliary Tree: Possible causes include biliary-enteric anastomosis or biliary fistula.
    • Imaging for Renal Tract Calcifications: Magnetic resonance imaging is significantly more sensitive than plain film radiography.
    • MR Urography Imaging Phase: Collecting systems are imaged during excretory phase (10-20 min) using 3D gradient echo and fat suppression.
    • Chemical Shift Imaging Characteristic for Lipid-Rich Benign Adenomas: Decreased signal compared to in-phase studies.
    • Cystourethrography Complication: Perforation is the most serious complication of bladder filling during the procedure.
