Continuous attractors for dynamic memories.

Episodic memory has a dynamic nature: when we recall past episodes, we retrieve not only their content, but also their temporal structure. The phenomenon of replay, in the hippocampus of mammals, offers a remarkable example of this temporal dynamics. However, most quantitative models of memory treat memories as static configurations, neglecting the temporal unfolding of the retrieval process.

Follow-up of multicentric HCC according to the mRECIST criteria: role of 320-Row CT with semi-automatic 3D analysis software for evaluating the response to systemic therapy.

Aim: To evaluate the role of 320-detector row computed tomography (MDCT) with 3D analysis software in follow up of patients affected by multicentric hepatocellular carcinoma (HCC) treated with systemic therapy by using modified response evaluation criteria in solid tumors (mRECIST).

Patients And Methods: 38 patients affected by multicentric HCC underwent MDCT. All exams were performed before and after iodinate contrast material intravenous injection by using a 320-detection row CT device.

Breast US as primary imaging modality for diagnosing gynecomastia.

Aim: To assess the role of breast US in diagnosing and classifying gynecomastia as the primary imaging modality and to compare US findings and classification system with the mammographic ones.

Patients And Methods: 48 patients suspected of having gynecomastia underwent mammography and US. Two radiologists in consensus retrospectively evaluated mammograms and sonograms.

PIP breast implants: rupture rate and correlation with breast cancer.

Aim: To evaluate the incidence of Poly Implant Prosthése (PIP) rupture as assessed by magnetic resonance imaging (MRI), the prevalence of the detected signs and the potential correlation with breast carcinoma.

Patients And Methods: 67 patients with silicone breast implants and clinical indications for breast MRI were evaluated for a total of 125 implants: 40 (32%) PIP in 21 patients and 85 non-PIP in 46 patients (68%), the latest considered as control group. A 1.

Diabetic mastopathy: a diagnostic challenge in breast sonography.

Purpose: Our purpose was to retrospectively evaluate the incidence and morphologic features of diabetic mastopathy in a group of patients with diabetes, searching for specific sonographic characteristics of diabetic mastopathy.

Methods: One hundred twenty diabetic patients underwent breast clinical examination, mammography, and sonography. All detected breast lesions were confirmed histopathologically.
