PURPOSE To assess the capability of echo-planar diffusion-weighted magnetic resonance imaging (MRI) (EPI-DWI) in diagnosing relapsing/residual cholesteatomas after canal wall-up mastoidectomy. MATERIALS AND METHODS In a blinded study design, we investigated with MRI, including standard spin-echo sequences, 18 patients evaluated with clinical examination(More)
This study aimed to evaluate the role of contrastenhanced magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) in the assessment of local recurrence of rectal cancer. Among 200 patients scheduled for CT follow-up, 60 (48 low risk; 12 high risk) were selected due to CT findings suspicious for or suggestive of local(More)
The effect of carotid artery stenting (CAS) on cognitive function is still debated. Cerebral microembolism, detectable by post-procedural diffusion-weighted imaging (DWI) lesions, has been suggested to predispose to cognitive decline. Our study aimed at evaluating the effect of CAS on cognitive profile focusing on the potential role of cerebral microembolic(More)
This study was undertaken to assess the reliability of the posterior approach under ultrasonographic guidance (PAUGA), with the arm abducted, before performing direct magnetic resonance (MR) arthrography of the shoulder. A total of 111 (82 men, 29 women; mean age, 24 years) underwent direct MR arthrography of the shoulder. Patients were enrolled because of(More)
PURPOSE To assess the utility of echo-planar diffusion-weighted magnetic resonance imaging (EPI-DWI) in the diagnosis of secondary cholesteatoma of the middle ear and in the differential diagnosis between residual/relapsing cholesteatoma and non-cholesteatomatous tissues (scar, granulation and inflammatory tissue) after conservative mastoidectomy.

Percutaneous lung biopsies (PLBs) performed for the evaluation of pulmonary masses require image guidance to avoid critical structures. A new CT navigation system (SIRIO, “Sistema robotizzato assistito per il puntamento intraoperatorio”) for PLBs was validated. The local Institutional Review Board approved this retrospective study. Image-guided PLBs in 197(More)
Arteriovenous malformation (AVM) of the pancreas is a rare condition. Most patients are asymptomatic or alternatively may present with a wide spectrum of symptoms. Traditionally, surgery has been considered the treatment of choice; however, alternative approaches, such as transcatheter embolization (TAE), may be proposed. We report a case of a 48-year-old(More)
Background: At early stages, the diagnosis of local recurrence of rectal cancer is often difficult and magnetic resonance imaging (MRI) is currently considered the most accurate method for diagnosing recurrence. We evaluated the role of unhenhanced and gadolinium-enhanced MRI for the diagnosis of local recurrence of rectal cancer. Methods: Thirty-six(More)
To compare patients’ radiation exposure, technical feasibility, imaging quality and complication rate of percutaneous lung biopsies (PLBs) performed with a low-dose (LD) CT protocol under guidance of an optical navigation system. Fifty-two consecutive patients with suspected malignant lung lesions were enrolled and randomised into group 1 (PLBs under the(More)
Bone metastases can be treated by interventional radiologists with a minimally invasive approach. Such treatments are performed percutaneously under radiological imaging guidance. Different interventional techniques can be applied with curative or palliative intent depending on lesions and patients' status. In the whole, available interventional techniques(More)
