Diffuse Bronchiectasis Secondary to Chronic Airways Infection: Thin-Section CT Evaluation
Bronchiectasis and bronchiolectasis are defined as irreversible airways dilation of the central and peripheral bronchi, respectively. Bronchiectasis is a common finding on thin-section ( (Source: Contemporary Diagnostic Radiology)

Breast Cancer Masquerading as a Benign-Appearing Mass
Most invasive breast cancers appear as irregular or spiculated masses; however, 10% to 20% of breast malignancies can appear relatively circumscribed.1 Less common types of malignant breast masses can present as round or oval masses with predominantly circumscribed margins. These include mucinous carcinoma, medullary carcinoma, papillary carcinoma, malignant phyllodes tumors, high-grade triple-negative invasive ductal carcinoma, lymphoma, and metastases. Consideration of imaging features across all modalities and use of the clinical presentation may suggest one of these diagnoses over more common benign entities. (Source: ...

The Many Uses of Chemical Shift Imaging in Body MRI
Chemical shift imaging is a relatively fast MR sequence, which is valuable in characterizing pathologies in multiple organ systems to help narrow the differential diagnosis or make a definitive diagnosis. Characterization by chemical shift imaging is based on three principles: detection of intracytoplasmic lipid, India-ink artifact, and susceptibility artifact.

Bronchopulmonary Sequestration: Spectrum of Appearance on CT
Bronchopulmonary sequestration is an uncommon pulmonary disorder consisting of a segment of nonfunctioning lung parenchyma that lacks communication with the tracheobronchial tree.1,2 Bronchopulmonary sequestration receives its primary arterial blood supply from an aberrant systemic artery, usually originating from the thoracic or abdominal aorta. Venous drainage can be either to pulmonary or systemic veins.1 The prevalence of bronchopulmonary sequestration ranges from 1% to 6%. The predominant sex and age of presentation is variable depending on the type of bronchopulmonary sequestration. Despite its low prevalence, bronch...

Unusual Tumors of the Lung
Adenocarcinoma and squamous cell carcinoma are the most common histologic subtypes of lung cancer, comprising nearly 70% of primary lung neoplasms.1 The remaining subtypes consist of other uncommon epithelial tumors, including neuroendocrine tumors, salivary gland-type tumors, mesenchymal tumors, lymphohistiocytic tumors, and tumors of ectopic origin, as reclassified by the World Health Organization in 2015.2 (Source: Contemporary Diagnostic Radiology)

Pitfalls in Cardiac CT: Causes and Solutions
Cardiac CT is used increasingly in the evaluation of cardiac abnormalities, particularly for coronary artery diseases. Cardiac CT mainly provides morphological information, but it also can generate some functional information. Cardiac CT can be performed either with prospective electrocardiogram (ECG) triggering or retrospective ECG gating. Several pitfalls can be seen in cardiac CT, and these can be confused for abnormal cardiac lesions. In this article, we provide solutions to avoid their misdiagnosis.

CT Imaging of Renovascular Abnormalities
Abnormalities of the renal vasculature can manifest clinically as renal ischemia, renal insufficiency, and secondary hypertension. It is crucial to inspect the renal vessels not only for intrinsic or direct causes of vascular disease, but also for the enhancement pattern of the renal parenchyma as an indirect sign for vascular compromise. Although atherosclerotic renal artery stenosis is the most common renal vascular disease, fibromuscular dysplasia of the renal artery is the second most common and has characteristic imaging findings. Some vasculitides may affect the renal artery, and these need to be considered when ther...

Imaging Features and Complications of Female Urethral Diverticula
A female urethral diverticulum is a focal outpouching of the urethra into the urethrovaginal potential space.1 The reported incidence of urethral diverticula in women is approximately 1% to 6%, with the diagnosis typically occurring between the third and sixth decades of life.2 In symptomatic women, the classic clinical triad of dysuria, dyspareunia, and postvoid dribbling is present (the “three Ds”).1 However, women with urethral diverticula are more commonly asymptomatic or present with an array of nonspecific genitourinary symptoms such as urinary frequency and urgency, chronic or recurrent urinary tract infections,...
