LYMPHOSCORE (Lymphoscintigraphy Scoring Reliability) Reliability of a New Qualitative and Semiquantitative Lymphoscintigraphy Scoring System for Primary Lymphedema.

Purpose Of The Report: Primary lymphedema (PLE) is a rare chronic disorder. Extremity lymphoscintigraphy offers access for dynamic and functional information on peripheral lymphatics and lymph nodes. We aimed to assess intraobserver and interobserver reliability of a new lymphoscintigraphy quantitative and qualitative scoring system in a homogeneous population of adult patients followed for PLE of the lower limb(s).

Prevention of post-hepatectomy liver failure after major resection of colorectal liver metastases: is hepato-biliary scintigraphy the optimal tool?

Background: Liver failure is the most threatening complication after hepatectomy for colorectal liver metastases. Recent studies indicate that liver functional evaluation by hepatobiliary scintigraphy (HBS) could be more sensitive than volumetry to predict the risk of post-hepatectomy liver failure (PHLF). The aim of this study was to evaluate the performance of Tc-mebrofenin HBS, when used as the main preoperative assessment before major hepatectomy in patients with liver metastases from colorectal cancer.

Unusual Focal Lung Uptake without CT Abnormality on a Bone Scan: What Might It Mean?

A 48-year-old woman was referred for a bone scan as an assessment of bone metastasis from breast cancer. Surprisingly, two hot spots of lung uptake were present in the left lung without any abnormality on CT slices. No history of pulmonary disease was observed.

Tumor Targeting and Three-Dimensional Voxel-Based Dosimetry to Predict Tumor Response, Toxicity, and Survival after Yttrium-90 Resin Microsphere Radioembolization in Hepatocellular Carcinoma.

Purpose: To identify predictive factors of tumor response, progression-free survival (PFS), overall survival (OS), and toxicity using three-dimensional (3D) voxel-based dosimetry in patients with intermediate and advanced stage hepatocellular carcinoma (HCC) treated by yttrium-90 (Y) resin microspheres radioembolization (RE).

Materials And Methods: From February 2012 to December 2015, 45 Y resin microspheres RE procedures were performed for HCC (Barcelona Clinic Liver Cancer stage B/C; n = 15/30). Area under the dose-volume histograms (AUDVHs) were calculated from 3D voxel-based dosimetry to measure Y dose deposition.

Diagnosis of silent myocardial ischemia during the staging of HIV-associated lymphoma with FDG PET/CT.

Fasting 18F fluoro-deoxy-glucose positron emission tomography examinations are routinely performed for the staging of HIV-associated lymphomas. In addition to possible comorbidity factors, the chronic inflammation that occurs in HIV-infected patients together with the metabolic side effects of antiretroviral therapy increases the risk for coronary artery disease. Moreover, HIV-infected patients are likely to develop polyneuropathies due to the viral infection or to the side effects of long-term protease or nucleoside reverse transcription inhibitor treatments.
