To compare diffusion weighted whole body imaging with background body signal suppression (DWIBS) with hybrid Positron Emission Computed Tomography (HPET/CT) on clinical value in oncology. ⋯ DWIBS and HPET/CT have a certain degree of consistency in terms of identifying lesions. However, they have advantages and disadvantages in some organs or tissues, which should be taken into full consideration in clinical practice.

Recent literature revealed good short-term results after microfracturing (MFX) of isolated focal cartilage defects in the knee joint. Study purpose was a long-term evaluation of patients who received MFX through a multimodal approach, correlating clinical scores and morphological pre- and postoperative MRI-scans. ⋯ Our study demonstrated that MFX as a treatment option for cartilage defect in the knee did not show the anticipated clinical and radiological long-term results. In 12 of 15 patients the cartilage defect size had increased after MFX, in 2 patients indicating full-knee replacement. Especially those with a leg malalignment >5° in varus were more prone to suffer from an increase in defect size. In our cohort the clinical scores correlated with the radiological findings.

Comparative Study
Comparison of 3D vs. 2D fast spin echo imaging for evaluation of articular cartilage in the knee on a 3T system scientific research.
We sought to retrospectively compare the accuracy of a three-dimensional fat-suppressed, fast spin-echo sequences acquired in the sagittal plane, with multiplanar reconstructions to that of two-dimensional fat-suppressed, fast spin echo sequences acquired in three planes on a 3T MR system for the evaluation of articular cartilage in the knee. ⋯ There was no significant difference in accuracy for the evaluation of articular cartilage of a single three-dimensional, fast spin echo sequence with multi-planar reformatted images vs. two-dimensional, fast spin echo sequences acquired in all three imaging planes in the knee.

To evaluate the efficiency and feasibility of microwave (MW) ablation assisted by a real-time virtual navigation system for hepatocellular carcinoma (HCC) undetectable by conventional ultrasonography. ⋯ MW ablation assisted by a real-time virtual navigation system is a feasible and efficient treatment of patients with HCC undetectable by conventional ultrasonography.

To assess the value of sonographic criteria, based on measurements of joint capsule distension and synovial hyperemia, during the course of repeated ultrasound (US)-guided intra-articular injections of hyaluronic acid (HA) in hand osteoarthritis (OA). ⋯ In this study, we demonstrate the meaningfulness of sonographic evaluation criteria including measurements of joint capsule distension and PDUS vascularization, both significantly correlating with the decrease of pain, during the therapy follow-up of US-guided intra-articular HA-injections in patients with hand OA.
