Fetal magnetic resonance imaging of acquired and developmental brain anomalies.

During the last decade, increasing interest in magnetic resonance imaging has emerged for the evaluation of fetal abnormalities detected on ultrasound. The advent of single-shot rapid acquisition sequences has greatly facilitated our ability to obtain detailed imaging information of the fetal brain. To date, fetal magnetic resonance imaging has shown to have an important role in the investigation of cerebral abnormalities suspected by sonography, and in the detection of subtle brain anomalies associated with high-risk pregnancies.

MR imaging of brain maturation.

Magnetic resonance imaging (MRI) is the imaging tool of choice to evaluate brain maturation and especially brain myelination. Magnetic resonance imaging also provides functional insight through diffusion images and proton spectroscopy. In this review the MRI techniques are analyzed for both pre- and postnatal periods.

[Role of [18]-FDG PET/CT in the initial staging of head and neck cancers].

Objective: To evaluate the impact of fusion of positron emission tomography with computed tomography (FDG-PET/CT) in the initial staging of head and neck carcinomas.

Methods: This retrospective study included 44 patients with squamous cell carcinoma of the upper aerodigestive tract. Patients underwent a standard workup and a PET/CT image fusion during the initial staging.

[Contribution of 18FDG PET/CT post treatment surveillance of head and neck squamous cell carcinoma].

Objective: To evaluate the contribution of 18FDG positron emission tomography for the post treatment surveillance of head and neck carcinomas.

Methods: : This prospective study included 61 patients with advanced squamous cell carcinoma of the upper airways and/or digestive tract and who underwent curative treatment. Patients underwent a standard workup (physical examination, CT scan and panendoscopy) and a PET/CT image fusion 3 months after the end of treatment.
