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 T1 -weighted imaging (T1 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 co…

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 demonst…

PURPOSE: To 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 METHODS: In thi…

PURPOSE: To determine the optimal slice thickness, playback rate, and scan time for uterine peristalsis with 3.0T magnetic resonance imaging (MRI). MATERIALS AND METHODS: In all, 23 young female volunteers underwent a 3.0T MRI scan with di…

PURPOSE: To evaluate the ability of automated software to quantify uterine peristalsis on cine magnetic resonance imaging (MRI). MATERIALS AND METHODS: At 1.5T, half-Fourier acquisition single-shot turbo spin echo (HASTE) techniques were u…

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 determine the optimal single shot fast spin echo (SSFSE) technique by varying interval between image acquisitions for cine MRI of uterine peristalsis. MATERIALS AND METHODS: MRI was performed in 13 premenopausal women (4 normal…

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…

We describe a 37-year-old patient who presented with right lower quadrant pain and intermenstrual bleeding. MRI demonstrated a 5 x 5 cm lobulated mass centered in the right uterine wall interpreted as suspicious for malignancy. A total hyst…

PURPOSE: To evaluate the capability of a newly developed semiautomatic analysis technique for evaluation of uterine peristalsis in comparison with visual assessment. MATERIALS AND METHODS: Cine magnetic resonance (MR) images were obtained …

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 demonstrate and evaluate uterine peristalsis on cine magnetic resonance imaging (MRI) using ultrafast imaging. MATERIALS AND METHODS: Serial MR uterine images (300) were obtained from 15 normal volunteers over four menstrual ph…

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. …

PURPOSE: To evaluate the magnetic resonance (MR) venographic appearance of the ovarian veins in a healthy population, correlated with surgical findings. Our data can be used as a basis for comparison to patients with suspected pelvic conges…
