Which measurement method should be used for prostate volume for PI-RADS? A comparison of ellipsoid and segmentation methods
Prostate volume and PSA density (PSAd) are important in the risk stratification of suspected prostate cancer (Pca). PI-RADS v2.1 allows for determining volume via segmentation or ellipsoid calculation. The purpose of our study was to compare ellipsoid and segmentation volume calculation methods and evaluate if PSAd diagnostic performance is altered. (Source: Clinical Imaging)

Unveiling the unreal: Comprehensive imaging review of hepatic pseudolesions
Hepatic pseudolesions are defined as non-neoplastic focal abnormalities of the liver which can mimic or conceal true liver lesions. It is particularly common in liver due to its unique dual blood supply and the existence of multilevel anastomosis between them. Because of the recent advances in CT and MRI technology, they are being increasingly encountered in daily practice. Broadly they can be categorised in to (1) Focal parenchymal abnormalities like focal fatty change, focal fat sparing, focal confluent fibrosis, segmental hypertrophy and regenerative nodules, (2) Perfusion abnormalities which include transient hepatic p...

Post-dural puncture pseudomeningocele ( “arachnoid bleb”): An underrecognized etiology of spontaneous intracranial hypotension symptomatology
Spontaneous intracranial hypotension (SIH) is an important secondary cause of a persistent headache syndrome, classically presenting as sudden onset debilitating positional headaches related to reduced intracranial cerebrospinal fluid (CSF) volume. Current understanding of SIH pathogenesis recognizes three underlying etiologies: dural tear, meningeal diverticulum, and CSF-venous fistula, with a fourth broad category of indeterminate/unknown etiologies. Post-dural puncture headache (PDPH) is a well-known and common complication of dural puncture, typically remitting spontaneously within two weeks of onset or with autologous...

Review of multi-modality imaging update and diagnostic work up of Takotsubo cardiomyopathy
Takotsubo cardiomyopathy (TC) is an acute but reversible non-ischemic heart failure syndrome. It is characterized by a transient form of ventricular dysfunction typically manifesting as basal hyperkinesis with hypokinesia and ballooning of left ventricle mid-cavity and apex. Imaging helps in both diagnosis and follow up. Echocardiogram is the first-line modality to assess the typical contractile dysfunction in suspected patients with catheter angiography showing normal coronary arteries. Cardiac MRI is currently the modality of choice for the non-invasive initial assessment of TC and for follow up imaging. (Source: Clinical Imaging)

Screening mammography mitigates breast cancer disparities through early detection of triple negative breast cancer
Screening mammography improves breast cancer survival through early detection, but Triple Negative Breast Cancer (TNBC) is more difficult to detect on mammography and has lower survival compared to non-TNBC, even when detected at early stages. TNBC is twice as common among African American (AA) compared to White American (WA) women, thereby contributing to the 40% higher breast cancer mortality rates observed in AA women. The role of screening mammography in addressing breast cancer disparities is therefore worthy of study. (Source: Clinical Imaging)

Focal hepatic intrinsically hyperattenuating lesions at unenhanced CT: Not always calcifications
Due to the growing use of CT, there has been an increase in the frequency of detecting focal liver lesion. Intrinsically hyperattenuating hepatic lesions or pseudolesions are not uncommon at unenhanced CT. Hyperattenuating hepatic lesions can be divided into non-calcified and calcified.Causes of intrinsic hyperattenuation include hemorrhage, thrombosis, and calcifications. Focal liver lesions can show hyperattenuation on unenhanced CT in case of severe liver steatosis.Recognition of etiologies associated with hyperattenuation on unenhanced CT can help the radiologist in characterizing focal liver lesions and pseudolesions....

Posterior trans-mediastinal lung herniation in a postoperative Marfan's patient
Thoracic hernias are defined as the protrusion of contents either into or outside of the thoracic cavity. These hernias can be acquired or congenital and occur in varying locations. Acquired thoracic hernias typically develop after surgery or trauma. The most common form is intercostal herniation due to thoracotomy. Trans-mediastinal herniation of the lung is even less common, typically seen in patients with sequestration, scimitar syndrome, or pneumonectomy, and, when present, commonly occurs across the anterior mediastinum.
