MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascu…

Endometriosis is a chronic multisystem disease caused by the presence of endometrium-like tissue outside the endometrial canal, inciting inflammation and fibrosis. Transvaginal ultrasound (TVUS) and MRI have replaced diagnostic laparoscopy …

BACKGROUND: A referenced MRI-based classification associated with focused ultrasound ablation surgery (FUAS) outcomes is lacking in adenomyosis. PURPOSE: To identify an MRI-based classification system for informing the FUAS outcomes. STUD…

BACKGROUND: Pelvic ultrasound (US) diagnosis of uterine fibroids may overlook coexisting gynecological conditions that contribute to women's symptoms. PURPOSE: To determine the added value of pelvic MRI for women diagnosed with symptomatic …

BackgroundThe yield of whole-body MRI for preventive health screening is currently not completely clear.PurposeTo systematically review the prevalence of whole-body MRI findings in asymptomatic subjects.Study typeSystematic review and meta-…

Background Endometrioma generally shows higher intracystic signal intensity (SI) than mucinous cystadenoma (MCA) on T 1 ‐weighted imaging (T 1 WI). Nonendometrioma‐associated malignant ovarian epithelial tumors (nonendometrioma group) often…

BACKGROUND: The diffusion-weighted imaging (DWI) signals of the female pelvic bone marrow show great variability and are usually high in female patients with fibroid-associated symptoms and anemia. PURPOSE: To ascertain clinical factors con…

Purpose To investigate the feasibility of three‐dimensional MR neurography (3D MRN) for the sacral plexus using sampling perfection with application‐optimized contrasts using different flip angle evolution (SPACE) sequences, and to demonstr…

PurposeTo compare the clinical usefulness of reduced field-of-view diffusion-weighted imaging (rFOV) with other imaging techniques in determining the depth of myometrial invasion (DMI) in endometrial cancer.Materials and methodsIn this pros…

PurposeTo identify parameters associated with ovarian malignancy using multiparametric quantitative magnetic resonance imaging (MRI).Materials and methodsAfter Institutional Review Board (IRB) approval, women with ovarian masses underwent p…

Diffusion-weighted imaging (DWI) is an established functional imaging technique that interrogates the delicate balance of water movement at the cellular level. Technological advances enable this technique to be applied to whole-body MRI. Th…

PURPOSE: To compare the diagnostic accuracy of MRI and "tenderness-guided" transvaginal ultrasonography (tg-TVUS) in the identification of recto-sigmoid endometriosis. MATERIALS AND METHODS: Institutional Review Board approval for this stu…

PURPOSE: To assess the value of magnetic resonance (MR) diffusion-weighted imaging (DWI) in the evaluation of deep infiltrating endometriosis (DIE). MATERIALS AND METHODS: In a prospective single-center study, DWI was added to the standard…

PURPOSE: To assess the value of magnetic resonance (MR)diffusion-weighted imaging (DWI) in the evaluation of deep infiltrating endometriosis (DIE). MATERIALS AND METHODS: In a prospective single-center study, DWI was added to the standard …

PURPOSE: To evaluate the usefulness of MRI jelly method (jelly method). MATERIALS AND METHODS: Fifty-five patients (32.7 +/- 5 years old) with endometriosis, treated with laparoscopic surgery between January and June 2005 with preoperative…

PURPOSE: To evaluate the usefulness of the three-dimensional half-Fourier RARE sequence in comparison with single-shot two-dimensional half-Fourier RARE and conventional fast spin echo (FSE) for female pelvic imaging. MATERIALS AND METHODS…

PURPOSE: To evaluate uterine changes on MRI before and after GnRH analog (GnRHa) treatment in diffuse adenomyosis. MATERIALS AND METHODS: Thirty-one patients with MRI features suggestive of diffuse adenomyosis received GnRHa for 6 months. D…

In 49 patients who had pelvic abnormalities, breath-hold T2-weighted fast-recovery (FR)-fast spin-echo (FSE) (imaging time = 24 sec) and nonbreath-hold FSE MR images (2 min 8 sec) were compared qualitatively (on a four-point scale) and quan…

This study compared one routine T2-weighted fast spin echo (T2FSE) sequence with a breath-hold T2FSE (BH T2FSE) sequence of the female pelvis for image quality, uterine anatomy, lesion detection, and signal intensity measurements. Thirty-tw…

Adenomyosis of the uterus is most often seen as focal or diffuse thickening of the myometrial junctional zone on MRI. We describe the morphologic features and signal characteristics of the rarer cystic form of the disease, as revealed by MR…

Our objective was to evaluate the efficacy of MR imaging as compared with conventional hysterosalpingography (HSG) for the detection of fallopian tube patency after uterine injection of contrast material. Rabbit uterine horns (n= 18) were c…

Suspected pelvic endometriosis was prospectively evaluated in 31 women with T1- and T2-weighted conventional spin-echo (CSE) magnetic resonance imaging alone and in combination with T1-weighted fat-suppressed (T1FS) and gadolinium-enhanced …

Abstract A total of 206 nongravid patients with various gynecologic problems underwent pelvic magnetic resonance (MR) examinations that included both sagittal T2‐weighted and contrast agent–enhanced T1‐weighted images. MR images were retros…
