Extent of pulmonary thromboembolic disease in patients with COVID-19 on CT: relationship with pulmonary parenchymal disease.

Aim: To report the severity and extent of pulmonary thromboembolic disease (PTD) in COVID-19 patients undergoing computed tomography pulmonary angiography (CTPA) in a tertiary centre.

Materials And Methods: This is a retrospective analysis of COVID-19 patients undergoing CTPA over a period of 27 days. The presence, extent, and severity of PTD were documented.

An audit of mammographic screen detected lesions of uncertain malignant potential (B3) diagnosed on initial image guided needle biopsy: how has our practice changed over 10 years?

Aim: To review all cases of B3 lesion diagnosed at initial image-guided needle biopsy over two 5-year cohorts to identify upgrade rates to malignancy and the effect of changing guidance on the management of such lesions.

Materials And Methods: Data was collected retrospectively. Mammographic features, biopsy type and management were recorded for each lesion.

Role of tomosynthesis in breast imaging going forward.

Digital breast tomosynthesis (DBT) is a modified mammographic technique that overcomes some of the limitations of full-field digital mammography (2DDM) by eliminating the effect of overlapping breast tissue. In the UK, DBT is utilised in both the symptomatic setting and in breast screening assessment clinics. A literature search was conducted from 2010-2017 to ensure that the most recent developments in DBT technology, clinical applications, and assessment of its usefulness in breast screening were reviewed.
