To evaluate diagnostic performance of endorectal magnetic resonance (eMR) for diagnosing local recurrence of prostate cancer (PC) in patients with previous radical prostatectomy (RP) and to assess whether contrast-enhanced (CE)-eMR improved diagnostic accuracy in comparison to unenhanced study. Unenhanced eMR data of 72 male patients (mean of total PSA:(More)
Epilepsy is the most frequent presenting sign in patients with cavernous angiomas and is the major cause of morbility. Persistence of seizures after surgical treatment prompted many authors to examine the possibility of removing the cavernoma and the surrounding tissue. In our series of 53 cavernous angiomas, all the 35 patients with preoperative seizures(More)
PURPOSE To describe the etiology, characteristics, and clinical evolution of epilepsy in patients with gelastic seizures (GSs). METHODS Nine patients whose seizures were characterized by typical laughing attacks were observed between 1986 and 1997. Patients were selected based on electroencephalogram (EEG) or video-EEG recordings of at least one GS and on(More)
PURPOSE Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) allows analysis of both tumor volume and contrast enhancement pattern using a single tool. We sought to investigate whether DCE-MRI could be used to predict histological response in patients undergoing primary chemotherapy (PCT) for breast cancer. PATIENTS AND METHODS Thirty patients(More)
The authors have examined the relationship between magnetic resonance imaging (MRI) and histopathological features in 35 surgically verified intracranial meningiomas. Tumor signals on T1-weighted images were rather similar regardless of the histologic subtype of the tumors. On T2-weighted images, hypointense meningiomas were mainly fibroblastic and(More)
The effects of a 12- to 24-month treatment with depot long-acting octreotide (OCT-LAR) on hormone profile, tumor mass, and clinical symptoms were reported in 36 patients with active acromegaly [GH, 34.2 +/- 5.6 microg/L; insulin-like growth factor I (IGF-I), 784.5 +/- 40.4 microg/L]. Fifteen patients were de novo whereas 21 had previously undergone(More)
Medical treatment of acromegaly with dopamine agonists possesses 2 main advantages: the oral administration and the low costs. In this study, we reported on the results of chronic treatments with quinagolide (CV 205-502), cabergoline (CAB) and long-acting depot preparation of bromocriptine (BRC-LAR) in 34 acromegalics. Patients were divided into three(More)
Cabergoline (CAB), a long-lasting dopamine-agonist, specific for the D2 receptor, is effective in normalizing serum PRL levels in most patients with microprolactinoma or idiopathic hyperprolactinemia. Because few data are presently available on the effects of CAB treatment in macroprolactinomas, the aim of this open-label study was to investigate whether(More)
Fourteen cases of intracranial lipomas are reported and 200 cases from the literature are reviewed. Intracranial lipomas are rare lesions of developmental origin, which mainly occur in the region of the corpus callosum, more rarely in the ambient, interpeduncular, cerebellopontine angle and sylvian cisterns. Although they are usually asymptomatic, they can(More)
The "default-mode" network is an ensemble of cortical regions that are typically deactivated during demanding cognitive tasks in functional magnetic resonance imaging (fMRI) studies. Using functional connectivity analysis, this network can be studied as a "stand-alone" brain system whose functional role is supposed to consist in the dynamic control of(More)
