Article Synopsis
- The study explores the use of a new imaging technique called deep learning-based reconstruction (DLR) to enhance MRI scans for better identification of multiple sclerosis (MS) lesions.
- Researchers compared the effectiveness of a high-resolution 1 mm-slice MRI (with DLR) to conventional 5 mm-slice MRI in detecting MS lesions in 42 patients.
- Results showed that the 1 mm T2-weighted MRI with DLR detected significantly more lesions than the standard method, especially in the brain stem, suggesting that this technique could be valuable in clinical practice.
Background: "Mid-flexion stability" is important for superior patient satisfaction following total knee arthroplasty (TKA). Thus, it is important to control medial joint gap intraoperatively as a countermeasure. However, reports on the precise intraoperative changes in medial joint gap during TKA are scarce.

Case Presentation: The patient was a 65-year-old man. Cerebral angiography demonstrated an aggressive dAVF involving the TSS, superior sagittal sinus (SSS), and the sinus confluence, with severe cortical and deep venous reflux.
We describe a 5-year-old castrated male dog suspected hypoglycemic encephalopathy that was evaluated by using diffusion-weighted imaging (DWI). The dog experienced hypoglycemia after prolonged generalized and continued partial seizures. In the acute phase, DWI showed hyperintensity in the left temporal lobe.

- The study aimed to find out if arterial spin labeling (ASL) can help distinguish between high signals in MR angiography (MRA) caused by reverse blood flow and those caused by arteriovenous shunting.
- Two radiologists analyzed data from 364 cases without arteriovenous shunting and 13 cases with dural arteriovenous fistula (DAVF) to compare signals on MRA and ASL.
- Results showed that ASL effectively differentiates reversal of venous flow from DAVF, although it may present false positives in some cases, particularly related to jugular vein flow.
