Decoding pylephlebitis: Tracing the path of infected thrombosis and liver abscesses.

Pylephlebitis, a septic thrombophlebitis of the portal vein, is an uncommon but serious complication following an abdominal site of infection, most frequently diverticulitis or appendicitis. It has a high mortality rate, yet it commonly presents with unspecific abdominal complaints and fever, making diagnosis by clinical and laboratory examinations alone, impossible. This report highlights the extensive computed tomography (CT) findings of pylephlebitis with multiple hepatic abscesses thought to be secondary to diverticulitis, in a patient presenting with septic shock.

Effect of CT reconstruction settings on the performance of a deep learning based lung nodule CAD system.

Purpose: To study the effect of different reconstruction parameter settings on the performance of a commercially available deep learning based pulmonary nodule CAD system.

Materials And Methods: We performed a retrospective analysis of 24 chest CT scans, reconstructed at 16 different reconstruction settings for two different iterative reconstruction algorithms (SAFIRE and ADMIRE) varying in slice thickness, kernel size and iterative reconstruction level strength using a commercially available deep learning pulmonary nodule CAD system. The DL-CAD software was evaluated at 25 different sensitivity threshold settings and nodules detected by the DL-CAD software were matched against a reference standard based on the consensus reading of three radiologists.

Computed Tomography Angiography with a 192-slice Dual-source Computed Tomography System: Improvements in Image Quality and Radiation Dose.

Purpose: This study aims to compare image quality, radiation dose, and the influence of the heart rate on image quality of high-pitch spiral coronary computed tomography angiography (CCTA) using 128-slice (second generation) dual-source CT (DSCT) and a 192-slice DSCT (third generation) scanner.

Materials And Methods: Two consecutive cohorts of fifty patients underwent CCTA by high-pitch spiral scan mode using 128 or 192-slice DSCT. The 192-slice DSCT system has a more powerful roentgen tube (2 × 120 kW) that allows CCTA acquisition at lower tube voltages, wider longitudinal coverage for faster table speed (732 m/s), and the use of iterative reconstruction.

Iron deficiency anemia as initial presentation of a non-small cell lung carcinoma: A case report.

Duodenal metastases secondary to lung cancer are very rare and most of the time asymptomatic. When symptomatic they usually present with bowel obstruction or perforation. We here describe the case of a 68 year-old man with a solitary metastasis in the duodenum from a non-small cell lung carcinoma (NSCLC).
