Radiation-induced pelvic insufficiency fractures are a frequent complication of radiation therapy for uterine cervical cancer. Osteolysis and avascular necrosis of the femoral head were also diagnosed using MRI after radiation therapy.

Diagnostic study, Level III.

Three-dimensional isotropic MR arthrography sequences with multiplanar reconstruction can provide a similar capability for the diagnosis of labral and rotator cuff lesions as conventional MR arthrography sequences but in a shorter imaging time.

An abundance of enhancing tissue in the rotator interval and thickening and enhancement of the axillary recess are signs suggestive of adhesive capsulitis on indirect MR arthrography.

The prevalence of a cyclops lesion was similar in both groups.

Isotropic 3D shoulder MR arthrography combined with a multiplanar reconstruction technique can help in the diagnosis of shoulder labral lesions as does 2D MR arthrography, but with shorter imaging times.

COVID-19, caused by SARS-CoV-2, is a contagious life-threatening viral disease that has killed more than three million people worldwide to date. Attempts have been made to identify biomarker(s) to stratify disease severity and improve treatment and resource allocation. Patients with SARS-COV-2 infection manifest with a higher inflammatory response and platelet hyperreactivity; this raises the question of the role of thrombopoiesis in COVID-19 infection. Immature platelet fraction (IPF, %) and immature platelet counts (IPC, 910 9 /l) can be used to assess thrombopoiesis. This study investigates whether the level of thrombopoiesis correlates with COVID-19 severity. A large cohort of 678 well-characterized COVID-19 patients was analyzed, including 658 (97%) hospitalized and 139 (21%) admitted to the intensive care unit (ICU). Elevated percentage IPF at presentation was predictive of length of hospitalization (P < 0Á01) and ICU admission (P < 0Á05). Additionally, percentage IPF at the peak was significantly higher among ICU patients than non-ICU patients (6Á9 AE 5Á1 vs 5Á3 AE 8Á4, P < 0Á01) and among deceased patients than recovered patients (7Á9 AE 6Á3 vs 5Á4 AE 7Á8, P < 0Á01). Furthermore, IPC at the peak was significantly higher among ICU patients than non-ICU patients (18Á5 AE 16Á2 vs. 13Á2 AE 8Á3, P < 0Á05) and among patients on a ventilator than those not (22Á1 AE 20Á1 vs.13Á4 AE 8Á4, P < 0Á05). Our study demonstrated that elevated initial and peak values of percentage IPF and IPC might serve as prognostic biomarkers for COVID-19 progression to severe conditions.
