Abstract Background Pelvic anterior–posterior compression (APC) fracture is typically associated with pelvic ligament damage. We used magnetic resonance imaging (MRI) to evaluate ligamentous injury associated with pelvic APC fracture. Methods Thirty healthy adults and 26 patients with pelvic APC fractures were enrolled in this study. All healthy adults underwent a series of MRI scans. Pelvic ligament visualization was scored [0 (poor) to 3 (excellent)] to identify the best scanning method. Then, MRI examination of patients with pelvic APC fracture was performed using this method. Results For healthy adults, oblique axial and axial scans provided the best visualization of the anterior sacroiliac ligament [ASL; good and excellent scores in 100% (30/30) and 96.7% (29/30) of cases, respectively; both P < 0.05 vs. coronal scans], followed by coronal scans [73.3% (22/30)]; sagittal scans provided poor visualization of this ligament (0%). Oblique sagittal scans provided the best visualization of the sacrotuberous ligament (SBL) and sacrospinous ligament [SPL; good and excellent scores in 90% (27/30) and 67.7% (20/30) of cases, respectively]. In patients with type I APC fracture, all three ligaments were intact without injury; in those with type III fracture, all three ligaments had ruptured. All type II APC fractures were associated with ASL rupture; the other two ligaments were injured simultaneously in 8 (42.1%) cases and two ligaments were uninjured simultaneously in 7 (36.8%) of these cases. Four patients had pubic symphysis separation > 30 mm, with no SBL or SPL injury; two patients had about 25 mm separation with SPL injury. Conclusion Healthy and injured pelvic ligaments can be evaluated using MRI; oblique axial and axial scanning are best for ASL visualization, and oblique sagittal scanning are best for SPL and SBL visualization. Pubic symphysis separation > 25 mm is not necessarily associated with SPL or SBL injury.

Objective: Surgical procedure and adjuvant treatment of type I endometrial cancer were affected by some variables assessed preoperatively. Diffusion-weighted magnetic resonance imaging (DWI) is a promising modality in evaluating myometrial invasion and cervical involvement, investigating the diagnostic values of DWI in assessing myometrial invasion and cervical involvement. Methods: A cross-sectional study was conducted. This study involved all type I endometrial cancer patients in Dr. Cipto Mangunkusumo Hospital from April 2016 until April 2019. The depth of myometrial invasion and cervical involvement was examined using 1.5-T MR unit. The result was compared to the surgical pathologic findings as the reference standard. Results: 34 types I endometrial cancer patients were enrolled in this study. The sensitivity of DWI in evaluating myometrial invasion and cervical involvement in type I endometrial cancer was 94.12% and 57.14%, while the specificity was 64.71% and 92.59%, respectively. Conclusion: DWI can provide reliable prognostic variable information about the myometrial invasion and cervical involvement in the preoperative preparation of endometrial cancer patients.

Abstract Objective: To evaluate by magnetic resonance imaging changes in bone marrow of patients undergoing treatment for type I Gaucher’s disease. Materials and Methods: Descriptive, cross-sectional study of Gaucher’s disease patients submitted to 3 T magnetic resonance imaging of femurs and lumbar spine. The images were blindly reviewed and the findings were classified according to the semiquantitative bone marrow burden (BMB) scoring system. Results: All of the seven evaluated patients (three men and four women) presented signs of bone marrow infiltration. Osteonecrosis of the femoral head was found in three patients, Erlenmeyer flask deformity in five, and no patient had vertebral body collapse. The mean BMB score was 11, ranging from 9 to 14. Conclusion: Magnetic resonance imaging is currently the method of choice for assessing bone involvement in Gaucher’s disease in adults due to its high sensitivity to detect both focal and diffuse bone marrow changes, and the BMB score is a simplified method for semiquantitative analysis, without depending on advanced sequences or sophisticated hardware, allowing for the classification of the disease extent and assisting in the treatment monitoring.

Objective: To present a strategy for identifying patients at risk of lymphatic failure in the setting of planned Fontan/Kreutzer completion, allowing a tailored surgical approach. Methods: Since January 2017, clinical evaluation before performance of the Fontan/Kreutzer procedure included T2-weighted magnetic resonance imaging (MRI) lymphangiography. Thoracic lymphatic abnormalities were categorized using a scale of I to IV according to progression of severity. Patients with severe lymphatic abnormalities (types III and IV) underwent Fontan/Kreutzer with lymphatic decompression via connection of the left jugular–subclavian junction containing the thoracic duct to the systemic atrium (group A). Results: Thirteen patients were enrolled. Magnetic resonance imaging showed type I abnormalities in four cases (30.7%), II in four (30.7%), III in two (15.3%), and IV in three (23.3%). Patients in types III and IV underwent a Fontan/Kreutzer with lymphatic decompression (group A, n = 5), while patients in types I and II underwent a fenestrated extracardiac Fontan/Kreutzer procedure without lymphatic decompression (group B, n = 8). Preoperatively, there were no differences in age, weight, ventricular dominance (right vs left), superior vena cava pressure, incidence of chylothorax after previous superior cavopulmonary anastomosis (Glenn), or need for concomitant procedures at Fontan/Kreutzer completion. There were no differences in procedural times between the groups, nor were there differences in mortalities and Fontan/Kreutzer takedowns. There were no statistically significant differences in early and late morbidity between the two groups with the exception of total volume of effusions output postoperatively. At median follow-up of 18 months (range, 4-28 months), all patients in group A are in New York Heart Association class 1 with no differences between groups in arterial oxygen saturation. Conclusions: Lymphatic decompression during Fontan/Kreutzer procedure was successfully performed in patients identified by MRI as predisposed to lymphatic failure. A larger cohort of patients and longer follow-up are required to determine the efficacy of this approach in preventing early- and long-term Fontan/Kreutzer failure.
