To compare adrenal gland volume in septic shock patients and control patients by using semi-automated volumetry. ⋯ The present study reports that with semi-automated software, adrenal gland volume can be measured easily and reproducibly. Adrenal gland volume was found to be nearly double in sepsis compared with control patients. The absence of increased volume during sepsis would appear to be associated with a higher rate of mortality and may represent a prognosis factor which may help the clinician to guide their strategy.

To demonstrate the accuracy of magnetic resonance tractograpghy (MRT) in localizing the cortical spinal tract (CST) close to brain tumours by using intraoperative electric subcortical stimulation. ⋯ Intraoperative MRT is a reliable technique for localization of CST. In all patients MEP were elicited by direct subcortical electrical stimulation at a distance below 1 cm from the CST as represented by MRT. Brain shifting might impact this evaluation since CST position may change during surgery in the range of 8 mm.

Comparative Study
Comprehensive imaging of residual/ recurrent nasopharyngeal carcinoma using whole-body MRI at 3 T compared with FDG-PET-CT.
To prospectively compare the diagnostic potential of 3-T wholebody magnetic resonance imaging (WB-MRI) and integrated fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) (FDG-PET-CT), and their combined interpretation for the detection of residual/recurrent nasopharyngeal carcinoma (NPC). ⋯ Three-Tesla WB-MRI achieved a similar diagnostic capability to FDGPET-CT for the detection of residual/recurrent NPC. Both techniques have different advantages, and their combined interpretation can yield a slightly higher diagnostic capability. In clinical practice, 3-T WB-MRI can offer an accurate and comprehensive assessment of residual/recurrent NPC.

To compare the image quality of computed tomography pulmonary angiography (CTPA) obtained with the injection of various low doses of contrast medium (CM) with different injection-related factors. ⋯ The use of proper injection-related factors during CTPA, such as a low trigger level and a high flow rate with saline injection following a decreased CM volume (55 ml or 50 ml), will enable adequate pulmonary artery contrast enhancement.

Clinical Trial
Improved in vivo detection of cortical lesions in multiple sclerosis using double inversion recovery MR imaging at 3 Tesla.
To investigate the impact of a higher magnetic field strength of 3 Tesla (T) on the detection rate of cortical lesions in multiple sclerosis (MS) patients, in particular using a dedicated double inversion recovery (DIR) pulse sequence. ⋯ DIR brain MR imaging at 3 T substantially improves the sensitivity of the detection of cortical lesions compared with the standard magnetic field strength of 1.5 T.
