AIM To assess computed tomography (CT) pulmonary angiography (CTPA) dose and image quality in a large teaching hospital, and subsequently, to optimise the protocol in order to reduce the dose without affecting image quality. MATERIALS AND METHODS Dose-length product (DLP), patient size, and objective quality parameters (contrast-to-noise ratio and signal-to-noise ratio on standardised levels)...

Abstract Background Displaced anterior segmental bronchus and pulmonary artery is extremely rare. A keen knowledge of such variations required in the field segmentectomy, for unawareness structural variation could lead to intra- postoperative complications. Case presentation 50-year-old female presented our department with suspected lung adenocarcinoma. Preoperative 3-dimensional computed tomog...

OBJECTIVES To investigate the feasibility of high-pitch CT pulmonary angiography (CTPA) in 3rd generation dual-source CT (DSCT) in unselected patients. METHODS Forty-seven patients with suspected pulmonary embolism underwent high-pitch CTPA on a 3rd generation dual-source CT scanner. CT dose index (CTDIvol) and dose length product (DLP) were obtained. Objective image quality was analyzed by c...

PURPOSE To evaluate if respiratory coaching performed prior to CT pulmonary angiography (CTPA) image acquisition has an impact on the occurrence of transient interruption of contrast (TIC) phenomenon. MATERIALS AND METHODS Two hundred and thirty-one consecutive patients with suspected pulmonary embolism (PE) were referred for CTPA. They were randomised into two groups, with or without respira...

Sagar A-ES, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-223503 Description A 38-year-old woman underwent an outpatient L5/S1 discectomy. The procedure was complicated by intraoperative bleeding, and haemostasis was achieved using a thrombin-based haemostatic matrix (TBHM). She presented to our facility on postoperative day 5 with left-sided chest pain and dyspnoea. CT pulmonary angiography (...

Partial anomalous pulmonary venous connection is a rare congenital anomaly in which one or more pulmonary veins are connected to the venous circulation. The condition is frequently misdiagnosed, and usually identified by transesophageal echocardiography or invasive cardiac catheterization. We present the case of a 26-year-old female with new onset dyspnea on exertion who was diagnosed with the ...
