Article Synopsis
- The study investigates the effectiveness of two brain tumor perfusion MRI techniques: dynamic susceptibility contrast-enhanced (DSC) and arterial spin labeling (ASL), focusing on their qualitative and quantitative diagnostic capabilities.
- A total of 90 patients treated for malignant brain tumors were analyzed, with imaged perfusion data being categorized into treatment-related changes or relapse/residual mass.
- Results show that DSC and ASL values are generally higher in relapse cases than in treatment-related changes, with strong correlations between the techniques, indicating potential overlapping effectiveness in diagnosis.
Article Synopsis
- The study aimed to evaluate the effectiveness of convolutional neural networks (CNNs) in quickly detecting strokes and classifying their vascular territory using diffusion-weighted images (DWI).
- Researchers created custom datasets from DWI images of 421 cases, including both stroke patients and healthy individuals, for training and testing the CNN models.
- Results showed that modified MobileNetV2 and EfficientNet-B0 models achieved high accuracy in detecting strokes (96% and 93%, respectively) and classifying them into specific types (middle cerebral artery or posterior circulation) with effectiveness around 93% and 87%.
Purpose: To investigate the association between the knee joint anatomical variations and pathologies, and to describe the quadriceps patellar tendon angle (QPA).
Methods: MRIs of 406 cases with a lateral patellar tilt angle (LPT)>5° and a control group of 40 cases with an LPT<5° were retrospectively evaluated. QPA, LPT, trochlear sulcus angle (TSA), tibial tubercle-trochlear groove distance (TT-TG), Insall-Salvati index (ISI), patellar tendon length (PTL), patellar height (PH), lateral trochlear inclination (LTI), trochlear facet asymmetry ratio (TFA) and trochlear depth (TD) were measured.
Purpose: Although the clinical use of multiparametric prostate magnetic resonance imaging (mpMRI) is increasing, the adherence to parameters for mpMRI, which had been described in the Prostate Imaging-Reporting and Data System version 2 (PI-RADS v2) for an optimum image acquisition is unknown. In this paper, we aimed to determine the compliance with the minimum acceptable technical parameters for prostate mpMRI defined by PI-RADS v2 in tertiary care centers in Turkey.
Methods: We sent a survey to all radiology departments of tertiary referral hospitals in Turkey (n=120) to evaluate their adherence to PI-RADS v2 technical specifications.
Developmental venous anomaly (DVA) is a common lesion formerly known as venous angioma. DVAs drain normal brain parenchyma; however, parenchymal abnormalities surrounding DVAs have been reported. Unilateral putamen and caudate calcification in the drainage territory of DVAs has so far been reported in 7 cases, all with deep venous drainage.
