Article Synopsis
- Researchers investigated whether a multiparametric scoring system (MSS) could enhance the accuracy of differentiating dementia with Lewy bodies (DLB) from Alzheimer's disease (AD) using brain imaging techniques.
- The study analyzed imaging data from 23 DLB patients and 57 AD patients, finding that certain Z-scores were significantly lower in DLB patients, while others were higher, indicating distinct imaging patterns between the two conditions.
- The MSS, which combines multiple imaging parameters, achieved an 82% diagnostic accuracy, surpassing the accuracy of individual imaging techniques in distinguishing between DLB and AD.
Background: Superficial siderosis (SS) results from chronic bleeding in the subarachnoid space. SS can be classified as infratentorial SS (i-SS) and supratentorial SS (s-SS). The cochlear modiolus (CM) normally shows low signal intensity (SI) on Tl-weighted images (T1WI).

Computed tomography-guided lung biopsy is a well-established method for the histological diagnosis of pulmonary lesions. There is abundant literature regarding the diagnostic yield of and complications associated with computed tomography-guided lung biopsy. Many studies have investigated the risk factors influencing pneumothorax.

Purpose: To determine whether conventional magnetic resonance imaging (MRI) using a multiparametric scoring system (MSS) is a useful way to predict PBS.
On conventional magnetic resonance imaging (MRI), hemangioblastomas typically appear as mural nodules with an adjacent surrounding cyst or a solid mass in the cerebellum. However, hemangioblastomas sometimes cannot be reliably distinguished using this imaging technique from other tumors, especially pilocytic astrocytomas and metastatic tumors, because of their similar imaging findings and locations. Herein, we report three cases of cerebellar hemangioblastomas and review their findings on conventional and advanced MRI, including diffusion-weighted imaging (DWI), dynamic susceptibility-weighted contrast-enhanced perfusion-weighted imaging (DSC-PWI), and magnetic resonance spectroscopy (MRS).
