Imaging is important for evaluation and diagnosis of nail pathologic disorders, and knowledge of imaging protocols and characteristics supports informed treatment planning and effective monitoring of therapeutic outcomes in cutaneous and systemic disease contexts.

Inferior vena cava (IVC) pathology is often underrecognized on non-dedicated imaging examinations, yet it carries significant diagnostic and clinical implications, particularly in acute emergency settings. This review highlights the complementary roles of ultrasound (US) and computed tomography (CT) in the assessment of IVC abnormalities. The US provides real-time, bedside evaluation of IVC patency, caliber, and hemodynamics, whereas CT offers detailed anatomic and structural characterization critical for diagnosis and management. The review aims to systematically discuss congenital variants, thrombotic, traumatic, systemic conditions, and neoplastic involvement of the IVC, emphasizing their imaging features and clinical relevance.
