Advantages of the Carr-Purcell spin-echo sequence in NMR tomography are discussed. It is pointed out that this method generates complete information about relaxation time T2 with only one measurement per slice as compared with the classic spin-echo method.

Background/purpose: In this study, we utilized magnetic resonance imaging data of the temporomandibular joint, collected from the Division of Oral and Maxillofacial Surgery at Taipei Veterans General Hospital. Our research focuses on the classification and severity analysis of temporomandibular joint disease using convolutional neural networks.
Materials And Methods: In gray-scale image series, the most critical features often lie within the articular disc cartilage, situated at the junction of the temporal bone and the condyles.

Background And Purpose: Irritable bowel syndrome (IBS) is a common bowel-brain interaction disorder whose pathogenesis is unclear. Many studies have investigated abnormal changes in brain function in IBS patients. In this study, we analyzed the dynamic changes in brain function in IBS patients using a Hidden Markov Model (HMM).

Purpose: Wide acceptance of arthroscopically treating posterolateral corner injuries has not occurred. There remains a fear of neurovascular (NV) injury while arthroscopically performing these reconstructions. The study's aim is to compare on Magnetic Resonance Scans the distance of the tibial tunnel in an arthroscopic popliteus tendon reconstruction (APB) and arthroscopic posterior cruciate ligament (PCL) reconstruction (APC) to the popliteal neurosvascular bundle.

Purpose: Conventional brain MRI protocols are time-consuming, which can lead to patient discomfort and inefficiency in clinical settings. This study aims to assess the feasibility of using artificial intelligence-assisted compressed sensing (ACS) to reduce brain MRI scan time while maintaining image quality and diagnostic accuracy compared to a conventional imaging protocol.
Patients And Methods: Seventy patients from the department of neurology underwent brain MRI scans using both conventional and ACS protocols, including axial and sagittal T2-weighted fast spin-echo sequences and T2-fluid attenuated inversion recovery (FLAIR) sequence.

In this manuscript, I comment on the article by Pospisilova published in the recent issue of the journal, in which selective embolization was used to treat anorectal hemangioma, a rare disease causing lower gastrointestinal bleeding. Anorectal hemangioma can easily be mistaken; for example, the patient in this case was previously misdiagnosed with ulcerative colitis. Choosing the appropriate tests and understanding the typical manifestations of anorectal hemangioma under colonoscopy, computerized tomography, magnetic resonance imaging and other tests are beneficial for diagnosis.
