A software program for automated compressive vertebral fracture detection on elderly women's lateral chest radiograph: Ofeye 1.0.

Background: Because osteoporotic vertebral fracture (OVF) on chest radiographs is commonly missed in radiological reports, we aimed to develop a software program which offers automated detection of compressive vertebral fracture (CVF) on lateral chest radiographs, and which emphasizes CVF detection specificity with a low false positivity rate.

Methods: For model training, we retrieved 3,991 spine radiograph cases and 1,979 chest radiograph cases from 16 sources, with among them in total 1,404 cases had OVF. For model testing, we retrieved 542 chest radiograph cases and 162 spine radiograph cases from four independent clinics, with among them 215 cases had OVF.

Retrospective Analysis of a New Prognostic Score for Diffuse Large B-Cell Lymphoma Based on Interim Positron Emission Tomography-Computed Tomography.

Background: The International Prognostic Index (IPI) scoring system is the most widely used prognostic tool for diffuse large B-cell lymphoma (DLBCL); however, it fails to consistently identify patients with poor outcomes. This retrospective study was undertaken to confirm the clinical value of a new prognostic score and compare it with the IPI.

Methods: The aim of this single-center study was to confirm the clinical value of a new prognostic score and its association with various clinical features, disease progression, and death in 70 patients with DLBCL who had undergone at least 6 cycles of chemotherapy.

Elderly population have a decreased aneurysmal subarachnoid hemorrhage incidence rate than Middle aged population: a descriptive analysis of 8,144 cases in mainland China.

Purpose: Rupture of an intracranial aneurysm is a life-threatening acute cerebrovascular event. The purpose of this study was to investigate whether aneurysmal subarachnoid haemorrhage (SAH) incidence rate is higher or lower in elderly population than in middle aged population.

Materials And Methods: Aneurysmal SAH cases were collected retrospectively from the archives of 21 hospitals in Mainland China.

Combined (11)C-methionine and 18F-FDG PET imaging in a case of cerebral sparganosis.

A 35-year-old man presented with right lower extremity numbness and weakness. CT demonstrated an irregular left parietal hypoattenuation with a punctuate calcification. MRI revealed a T1 low signal and T2 high signal lesion with extensive surrounding edema.
