Abstract:
Architectural distortion is the third most-common appearance of breast cancer and often is a subtle finding on mammography. In this article, we review a variety of breast diseases that may present as architectural distortion on mammography; review the utility of correlative imaging, such as ultrasound and magnetic resonance; and review appropriate management for these diagnoses. Primary causes include breast cancer, ductal carcinoma in situ, radial scar, complex sclerosing lesion, and fat necrosis. Secondary etiologies include previous breast surgery, trauma, and infection. Familiarity with imaging findings presenting as distortion on multimodality imaging will optimize detection and management of this subtle-yet-significant finding.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Radiological Investigation I: X-ray and CT
Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
