Article Synopsis
- - The study compares two different digital breast tomosynthesis (DBT) methods for breast cancer monitoring in patients with a history of breast cancer: 2-view 2D digital mammography with 2-view DBT versus 1-view digital mammography with 1-view DBT.
- - An analysis of clinical performance using real patient images showed that both DBT implementations had similar results regarding sensitivity, specificity, and area under the curve, regardless of lesion types or breast density levels.
- - The study suggests considering the 1-view methods for breast cancer surveillance due to lower radiation exposure, but further research with larger samples is needed to reach a solid conclusion.
Magnetic resonance imaging (MRI) in patients with congenital growth hormone deficiency (GHD) has revealed several morphological abnormalities of the hypothalamo-pituitary region which include hypoplasia of the anterior pituitary lobe, the absence or marked thinning of the pituitary stalk and ectopia of the posterior pituitary lobe (EPP). This triad of abnormalities is called pituitary stalk interruption syndrome (PSIS). Our study reports the imaging findings of 23 patients with idiopathic GHD and short stature who were examined by MRI.

Twenty-six patients (13♂ and 13♀) with uveal melanomas underwent MRI and US examination. The signal intensity of the tumors and retinal detachments were depicted using MRI.

The aim of our study was to evaluate the magnetic resonance imaging (MRI) and ultrasound (US) characteristics of cavernous hemangioma and their role in the differential diagnosis of orbital tumors. Eight patients with orbital cavernous hemangiomas, five women and three men with a mean age of 48 years were examined in a period of six years.

These lesions have characteristic radiological features but the differential diagnosis from parasellar meningiomas and schwannomas can be difficult. Preoperative diagnosis is important due to the risk of severe intraoperative bleeding and the complex neurovascular structures of the cavernous sinus.
