Bacteraemia and Associated Complications on Imaging as a Clue to Colorectal Malignancy.

Streptococcus gallolyticus (SG) - among other bacterial infections - is associated with colorectal malignancy and adenoma. It is reported that patients with SG bacteraemia have a concomitant colorectal tumour in 25-80% of cases. We present a case of a patient with complications of this septicaemia associated with a rectal adenocarcinoma, as an example of this important radiological and clinical correlation.

Chest CT Diagnosis of COVID-19: Accuracy using CO-RADS and CT-Involvement Scoring.

Objectives: Both Reporting and Data System (CO-RADS) and CT-involvement scores (CTIS) have been proposed for evaluation of COVID-19 on chest CT. The purpose of this single-center, retrospective study was to evaluate both scoring systems to diagnose COVID-19 infection in a high-prevalence area.

Materials And Methods: Chest CT datasets (n = 200) and available reverse transcription polymerase chain reaction (RT-PCR) on nasopharyngeal swab were included.
