“…The use of MRI for evaluation of Crohn's disease (4,5) and appendicitis is compelling considering that most patients are young and have a greater concern for ionizing radiation-induced malignancies from CT (13)(14)(15)(16). Other intraabdominal inflammatory processes shown to be delineated by T2W FS imaging includes diverticulitis (1,17) pancreatitis (18,19), pyelonephritis (20), cholecystitis (21), and for evaluation of the acute abdomen (8,19,22).…”

Purpose: To test the theoretical benefits of a spectral attenuated inversion-recovery (SPAIR) fat-suppression (FS) technique in clinical abdominal MRI by comparison to conventional inversion-recovery (IR) FS combined with T2-weighted (T2W) partial Fourier single shot fast spin echo (SSFSE).Materials and Methods: 1.5T MRI studies of the abdomen were performed in 28 patients with liver lesions (hemangiomas n ϭ 14; metastases n ϭ 14). T2W sequences were acquired using IR and SPAIR SSFSE. Measurements included retroperitoneal and mesenteric fat signal-to-noise (SNR) to evaluate FS; liver lesion contrast-to-noise (CNR) to evaluate bulk water signal recovery effects; and bowel wall delineation to evaluate susceptibility and physiological motion effects.Results: SPAIR-SSFSE images produce significantly improved FS and liver lesion CNR. The mean SNR of the retroperitoneal and mesenteric fat for SPAIR SSFSE was 20.5 Ϯ 10.2 (Ϯ1 SD) and 12.7 Ϯ 6.2, compared to 43.2 Ϯ 24.1 (P ϭ 0.000006) and 29.3 Ϯ 16.8 (P ϭ 0.0000005) for IR-SSFSE. SPAIR-SSFSE images produced higher CNR for both hemangiomas CNR ϭ 164 Ϯ 88 vs. 126 Ϯ 83 (P ϭ 0.00005) and metastases CNR ϭ 75 Ϯ 27 vs. 53 Ϯ 19 (P ϭ 0.007). Bowel wall visualization was significantly improved using SPAIR-SSFSE (P ϭ 0.002). Conclusion:The theoretical benefits of SPAIR over conventional IR FS translate into significant multiple improvements that can be measured on clinical abdominal MRI scans.

“…Стандартное для получения гистологического заключения выполнение диагностической тре-панобиопсии может в ряде случаев закончить-ся образованием длительно не заживающего молочного свища, что может осложнить прово-димое неоадъювантное лечение [8]. МРТ мо-лочной железы, где для лучшей визуализации используется контрастное вещество, небезо-пасно для плода, т. к. проникает через плаценту и, как показал эксперимент с животными, вы-зывает аномалии развития плода [9][10][11]. Свя-занная с ограничением диагностических воз-можностей постановка правильного диагноза отдаляет начало лечения, что также отражает-ся на его результатах [23].…”

Selection and design of the most appropriate imaging studies during an emergency involving pregnant and/or potentially pregnant female has been the topic of numerous recent articles. While radiation dose must be limited to the necessary amount, a cautious application must never be so severe as to compromise the ability to make the correct diagnosis. No one approach suits all facilities or all circumstances. All approaches need to be institution specific, and may be country or continent dependent. In this article we review our approach to this scenario.

MRI of Acute Abdominal and Pelvic Pain in Pregnant Patients

Abstract: The intrinsic safety of MRI and its ability to accurately show abdominal and pelvic disease in pregnant patients make it highly useful in the evaluation of these patients.
