Men with clinical suspicion of PCa undergo tissue sampling and based on features including the Gleason score, Prostate Specific antigen (PSA) levels and clinical tumor (T) stage, patients are risk stratified into 6 major groups based on National Comprehensive Cancer Netwo...

çoise Kraeber-Bodere Multiple myeloma (MM) is always preceded by an initial monoclonal gammopathy of undetermined significance (MGUS) that then develops into asymptomatic or smoldering multiple myeloma (SMM), which constitutes an intermediate clinical stage between MGUS and MM. According to a recent study, risk factors for faster MGUS to MM progression include an M protein of 1.5 g/dL or more and an abnormal free light chain ratio in patients with non-IgM MGUS. Therefore, the International Myeloma Working Group (IMWG) decided to recommend whole-body computed tomography (WBCT) for patients with high-risk MGUS in ...

Tibial slope measurements are important in guiding clinical decisions in the field of orthopedic surgery. However, there are multiple techniques across different medical imaging modalities and little is known about its impact on result and validity of the measurement. Therefore, the purpose of this study was to compare tibial slope measurements from lateral radiographs, magnetic resonance imaging (MRI) and computed tomography (CT) scans in order to better assess the clinical significance of measured tibial slope values.

CONCLUSIONS: Careful implementation of hybrid medical imaging can clearly improve the quality of the diagnosis in cancer patients and even increase the quality of care for cancer patients. Close interdisciplinary collaboration is essential to optimize therapeutic strategies for each patient. PMID: 32052117 [PubMed - as supplied by publisher]

Abstract CLINICAL/METHODICAL ISSUE: Conventional imaging tests like computed tomography (CT) cannot visualize somatostatin receptor (SSTR) expression on the tumor cell surface. STANDARD RADIOLOGICAL METHODS: For imaging of SSTR-expressing tumors conventional morphological imaging tests such as CT or magnetic resonance imaging (MRI) are employed. METHODICAL INNOVATIONS: Molecular imaging of SSTR expression on the tumor cell surface, in particular by using (whole body) single photon emission computed tomography (SPECT) and positron emission tomography (PET), are considered the current standard of care. Onl...

ConclusionsIsolated agenesis of the corpus callosum is not innocuous, and patients with this defect require a strict neurocognitive follow-up. We provide an informative reference tool useful for the postnatal neuropsychological screening of patients with isolated agenesis of the corpus callosum.

The urachus revisited: Multimodal imaging of benign &malignant urachal pathology. Br J Radiol. 2020 Feb 11;:20190118 Authors: Das JP, Vargas HA, Lee A, Hutchinson B, O'Connor E, Kok HK, Torreggiani W, Murphy J, Roche C, Bruzzi J, McCarthy P Abstract The urachus is a fibrous tube extending from the umbilicus to the antero superior bladder dome that usually obliterates at week 12 of gestation, becoming the median umbilical ligament. Urachal pathology occurs when there is incomplete obliteration of this channel during foetal development, resulting in the formation of a urachal cyst, patent urachus, u...

AbstractImaging plays an increasing role in prostate cancer diagnosis and staging. Accurate staging of prostate cancer is required for optimal treatment planning. In detecting extraprostatic cancer and sites of early recurrence, traditional imaging methods (computed tomography, magnetic resonance imaging, radionuclide bone scan) have suboptimal performance. This leaves a gap between known disease recurrence as indicated by rising prostate-specific antigen and the ability to localize the recurrence on imaging. Novel positron emission tomography (PET) agents including radiolabeled choline, fluciclovine (18F-FACBC), and agent...

ConclusionsExtended PET/MRI acquisitions used to accommodate multiple MRI sequences may be associated with false ‐positive findings compared to PET/CT. PET/MRI is more likely to have incremental value when the prior probability for disseminated disease is low.
