Maximum tumor-absorbed dose measured by voxel-based multicompartmental dosimetry as a response predictor in yttrium-90 radiation segmentectomy for hepatocellular carcinoma.

Objective: Advances in hepatic radioembolization are based on a selective approach with radical intent and the use of multicompartment dosimetric analysis. The objective of this study is to assess the utility of voxel-based dosimetry in the quantification of actual absorbed doses in radiation segmentectomy procedures and to establish cutoff values predictive of response.

Methods: Ambispective study in hepatocarcinoma patients treated with radiation segmentectomy.

Relevance of [F]FDG-PET/CT in the detection of colon pathology, in patients studied by bacteriemia or infectious endocarditis caused by enteropathogenic microorganisms.

Purpose: Association between S. gallolyticus infective endocarditis (IE) and malignant lesions of the gastrointestinal tract is well described. We hypothesize that other enteropathogenic microorganisms, such as S.

Small rounded B-cell lymphoma of bone presented by limp, with a positive multifocal 99mTc MDP bone scintigraphy pattern and a negative 99mTc HMPAO-labeled leukocytes study.

In this article, we present a rare case of B-cell bone lymphoma in a child with multifocal asymptomatic lesions detected by bone scintigraphy and a chronic clinical history characterized by limping and fever episodes for over a year. Initially, multifocal osteomyelitis was suspected and antibiotic therapy was administered with no clinical improvement. The biopsy of the main lesion in the left distal femur along with bone marrow cytology established the final diagnosis.
