Methods And Materials: This retrospective study includes 25 patients with surgically proven acute bowel ischemia and 25 gender- and age-matched controls who underwent biphasic abdominal dual-energy CT. Two fellowship-trained abdominal radiologists and two residents evaluated all cases with and without additional dual-energy CT-derived iodine maps and virtual non-contrast images.
Article Synopsis
- In a study of six EAPDC cases, histological features were similar to axial PDC, showing malignant cell characteristics, and genetic analysis revealed common loss of the SMARCB1 gene.
- Follow-up revealed significant clinical challenges, including local recurrences and metastasis within months of surgery, highlighting the aggressive nature and poor prognosis of these rare tumors.
Background: Progressive collapsing foot deformity (PCFD) remains challenging to treat. Surgical planning depends on the amount and complexity of the deformity, which requires accurate differentiation through precise imaging. Weightbearing CT (WBCT) imaging has enhanced the three-dimensional (3D) assessment of PCFD.

- - The study aimed to compare the quality and effectiveness of deep learning reconstructed (DLR) 0.55 T MRI against the conventional 3 T MRI for identifying and grading knee injuries in trauma patients.
- - Conducted on 26 patients, the study involved paired MRI scans, where four radiologists assessed the images based on quality, structural anomalies, and their confidence in reporting findings.
- - Results indicated that DLR 0.55 T MRI achieved good image quality and nearly perfect agreement with 3 T MRI in identifying anomalies, proving it as a reliable alternative with high confidence levels from radiologists.
