ABSTRACT

PURPOSE: To compare efficancy of three-dimentional SPACE (sampling perfection with application-optimized contrasts using different flip-angle evolutions) and CISS (constructive interference in steady state) sequences in the imaging of the cisternal segments of cranial nerves V-XII. METHODS: Temporal MRI scans from 50 patients (F:M ratio, 27:23; mean age, 44.5±15.9 years) admitted to our hospital with vertigo, tinnitus, and hearing loss were retrospectively analyzed. All patients had both CISS and SPACE sequences. Quantitative analysis of SPACE and CISS sequences was performed by measuring the ventricle-to-parenchyma contrast-to-noise ratio (CNR). Qualitative analysis of differences in visualization capability, image quality, and severity of artifacts was also conducted. A score ranging 'no artefact' to 'severe artefacts and unreadable' was used for the assessment of artifacts and from 'not visualized' to 'completely visualized' for the assesment of image quality, respectively. The distribution of variables was controlled by the Kolmogorov-Smirnov test. Samples t-test and McNemar's test were used to determine statistical significance. RESULTS: Rates of visualization of posterior fossa cranial nerves in cases of complete visualization were as follows: nerve V (100% for both sequences), nerve VI (94% in SPACE, 86% in CISS sequences), nerves VII-VIII (100% for both sequences), IX-XI nerve complex (96%, 88%); nerve XII (58%, 46%) (p<0.05). SPACE sequences showed fewer artifacts than CISS sequences (p<0.002).

ABSTRACT

BACKGROUND: Our aim is to share our experiences regarding patients who cannot be fed effectively through the gastrostomy tube, but were inserted feeding jejunostomy through the gastrostomy orifice using scopic fluoroscopic techniques utilised by the interventional radiology. PATIENTS AND METHODS: Between January 2010 and May 2013 the patients that were inserted jejunostomy tube through the gastrostomy orifice using fluoroscopic techniques were retrospectively analysed. Data including primary indication for gastrostomy, sex, concomitant disease and the requirement for gastroesophageal reflux disease (GERD) were all recorded. RESULTS: There were five patients with these criteria. They all received either medical or surgical GERD therapy; nevertheless enteral feeding failed to reach an effective level, they all had vomiting and did not gain any weight. Following conversion, all the patients gained minimum 2 kg in 2-5 months; all the patients tolerated enteral feeding and were discharged in the early period. There were neither procedure related complications such as perforation, bleeding nor sedation related complications. Procedure took no more than 30 min as a whole. There was no need for surgical intervention. However in one patient re-intervention was required due to accidental removal of the catheter. CONCLUSIONS: In case of feeding difficulties following the gastrostomy; instead of an invasive surgical intervention; physicians should consider jejunal feeding that is advanced through the gastrostomy, which does not require any anaesthesia.
