The assessment of small bowel motility is a difficult task because of its complex nature. SPAMM or SPatial Modulation of the Magnetization is a strong<br />
candidate for a minimally invasive, observer independent method of motion assessment. The SPAMM method uses a prepulse to impose a lineshaped pattern<br />
on the magnetization. Upon readout, this pattern is distorted as a result of tissue motion between prepulse and readout. Originally developed for cardiac<br />
imaging, the SPAMM sequence was reconfigured for nonperiodic motion. The novel SPAMM technique was validated by focussing on the heartmotion,<br />
breathing motion and small bowel motility.<br />

The purpose of this study was to compare ultrafast imaging of the abdomen using multitransmit MR with routine, fast MR imaging in children and young<br />
adults who presented with acute abdominal pain to the emergency room.<br />
10 patients were studied. 5 were normal, and in the other 5 patients, correct diagnoses were made. Multitransmit MR imaging quality was rated the same or<br />
better in all cases. Improvements were noted in contrast, uniformity of fluid and fat signal, and less dielectric shading. Scan times were reduced, on<br />
average, by 48%. No sedation and no oral or intravenous contrast were needed.<br />

This study aimed for assessing the feasibility of in vivo trans-pyloric flow measurements by means of phase-contrast MRI. Dynamic EPI sequences were<br />
studied in vitro and applied in vivo behind the pylorus. The gained velocity, frequency and backflow percentage show very good agreement with literature<br />
values and give rise for expecting great potential in fast EPI phase-contrast MRI for dynamic quantification of trans-pyloric mass movements.<br />

Purpose: To evaluate the impact of MRI of the abdomen and pelvis in pregnant women on clinical and obstetrical management. Methods: Thirty one<br />
consecutive MRI studies of the abdomen of 29 pregnant patients, were included in the study Correlation between the MRI pathological findings related to<br />
the stage of pregnancy and the clinical and obstetric outcome were evaluated. Results: The indications for studies included: gynecologic conditions (9),<br />
suspected Crohn disease (7), suspected appendicitis (6), cancer staging and follow up (5), postoperative complications (3) and suspected pheochromocytoma<br />
(1). Conclusions: MR imaging proved to be appropriate in the management of pregnant patients with diverse abdominal pathology and could provide an<br />
accurate diagnosis prior to delivery in all patients.<br />

This study aims to identify the effect of maternal smoking during pregnancy on fetal lung and kidney growth. Pregnant women were scanned at 24th to 26th<br />
weeks and 34 to 36 weeks postconception. The lung and kidney MR images were analysed using semi automatic approach with Analyze software. Fetal lung<br />
and kidney volumes were reduced in the smoker group.<br />

This study aims to investigate the reliability of a MATLAB program designed to calculate the subcutaneous fat volume in the fetus. It will be employed in a<br />
study investigating macrosomia outcomes in diabetic pregnant mothers. The MR technique used to assess the foetal growth is Fat Sequences with Water<br />
Suppression where pregnant women were scanned in late pregnancy (after 30th gestation week) when fetal fat is more visible.
