OBJECTIVE To assess the prevalence and pattern of myocardial fibrosis as detected by delayed enhanced magnetic resonance imaging (DE-MRI) in patients with systemic sclerosis (SSc), and to evaluate a possible association between myocardial fibrosis and cardiac arrhythmias. METHODS Forty-one patients with SSc underwent 24-hour Holter monitoring, Doppler(More)
Neuroendocrine tumours (NETs) are highly vascularised tumours that express high levels of the vascular endothelial growth factor (VEGF) ligand together with its receptor VEGFR (Modlin et al. 2008). Although advanced NETs may exhibit a 30–40% response rate to combination chemotherapeutic approaches, the response to single-agent chemotherapy is only 10%(More)
The aim of this study is to evaluate the effect of iDose(4) iterative reconstruction algorithm on radiation dose and imaging quality at chest-abdomen-pelvis (CAP) CT examinations. Seventeen patients were considered; all patients had a previous CT scan with the standard filter back-projection (FBP) protocol and a follow-up scan with the iDose(4) protocol at(More)
BACKGROUND The diagnosis of inflammatory bowel disease (IBD) in children and adolescents is based on the integration of clinical, biological, endoscopic, histological and radiological data. METHODS The most important part of the diagnosis is the histology, which is acquired by endoscopy. Imaging of the small bowel has changed in recent years, but the(More)
Desmoid tumors are rare neoplasms arising at the site of any fascia. Although histologically benign, they can cause local infiltration and they also carry a risk of recurrence. We describe the case of an 11-year-old girl who presented with a desmoid tumor at the site of an old trauma, and we briefly review the literature of this lesion.
A carcinoid tumor of the pancreas (CTP) is a rare pancreatic neoplasm, and usually presents with carcinoid syndrome (CS). CS consists of the classic symptom triad of cutaneous flushing, diarrhea and valvular disease, and occurs in the majority of patients with liver metastases. In the present study, the patient presented with symptoms of CS. A diagnosis of(More)
Subclavian artery pseudoaneurysm and occlusion in young patients are usually post-traumatic. We report the case of a 33-year-old diabetic woman with subclavian artery occlusion and pseudoaneurysm formation caused by pulmonary mucormycosis infection. The patient presented with diabetic ketoacidosis, Horner’s syndrome, and absent left arm pulses. A cystic(More)
PURPOSE The study sought to prospectively evaluate which technique among T2-weighted images, dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI), diffusion-weighted (DW) MRI, or a combination of the 2, is best suited for prostate cancer detection and local staging. METHODS Twenty-seven consecutive patients with biopsy-proven adenocarcinoma of(More)
