Clinical imaging
-
This retrospective study aimed to describe the differences between image readings done with combined positron emission tomography/computed tomography (PET/CT) and PET read together with contrast-enhanced CT (ceCT) in patients with squamous cell carcinoma of the head and neck. In 46 patients, no differences were found between the two readings for assessing infiltration of adjacent structures (P=.63), transgression of the midline (P=.67), lymph node involvement (P=.32), and T- and N stage. PET/CT and PET read together with ceCT have comparable diagnostic yield.

The purpose of this study is to determine the clinical implication of small (<20 mm) enhancing hepatic nodules observed only at three-dimensional gadobenate dimeglumine-enhanced hepatic arterial-phase magnetic resonance imaging (MRI) of the hepatitis B virus-induced mild cirrhosis. ⋯ Small arterial-only enhancing nodules occult on the portal- and equilibrium-phase images as well as on the T1- and T2-weighted images are more likely to be HCC than nonneoplastic hypervascular benign lesions in patients with hepatitis B-induced mild cirrhosis.
