Episode 8: Liver Lesions Emphasizing Enhancement Characteristics and Pelvic Abscess
CASE 1 FREE PREVIEW ONLY: This program is a “Pay To View” program. To view the entire episode and obtain CME credits you must first purchase the program. Once purchased links will be provided from within your “MyAR Archives” page for access to the program and the online exam to earn CME credit.
Program Summary:
In this episode Dr Semelka describes a variety of hepatic conditions, benign and malignant, with an emphasis on evaluating early enhancement characteristics, hepatocyte-phase enhancement, and motion resistant strategies. A case of pelvic abscess is also shown, emphasizing the enhancement features of MRI.
Case 1: Multiple Transient hypervascular Hepatic Lesions. This case illustrates the differential diagnoses of multiple transient hypervascular hepatic lesions with ill-defined wedge-shape on hepatic arterial dominant phase.(FREE Preview Provided)
Case 2: Focal Nodular Hyperplasia. This case illustrates the typical findings of focal nodular hyperplasia in liver. Hepato-biliary specific contrast agent can differentiate focal nodular hyperplasia from hepatic adenoma, and discussion is made of contrast agents with hepatobiliary activity.
Case 3: Recurrent Hepatocellular Carcinoma with Motion Resistance Protocol. This case illustrates the recurrent hepatocellular carcinoma in liver. Description is made of the approach to employing a motion resistant protocol in a noncooperative patient.
Case 4: Focal Nodular Hyperplasia. This case illustrates the typical MR findings of focal nodular hyperplasia. Discussion is made of the role and type of follow-up study in a patient with suspected focal nodular hyperplasia.
Case 5: Recurrent Cholangiocarcinoma with Liver, Peritoneal, and Lung Metastases. This case illustrates MR findings of intrahepatic metastases following hepatectomy due to intrahepatic mass-forming cholangiocarcinoma. The ability of MRI to demonstrate disease in multiple organ systems is described.
Case 6: Abscess with Fistula in Lower Pelvis Following Total Colectomy. This case illustrates the MR findings of small abscess with fistula in lower pelvis following total colectomy. MRI can provide valuable information on abscess and fistula in the lower pelvis in patients with inflammatory bowel disease.
Approximate Episode Run Time: 53 Minutes
