161 Background: Multiparametric magnetic resonance imaging (mpMRI) used in conjunction with MR/TRUS fusion-guided biopsy has improved detection and localization of clinically significant prostate cancer. We aim to evaluate the utility of preoperative MRI characteristics to predict biochemical recurrence (BCR) following radical prostatectomy. Methods: Patients who underwent robotic assisted radical prostatectomy (RARP) between 2007-2014 at the National Institutes of Health were reviewed. We identified patients with BCR defined following the guidelines of the AUA Localized Prostate Cancer Update Panel report (serum PSA ≥0.2 ng/ml with a subsequent confirmatory value). Bivariate analysis and logistic regression were used to determine the association of mpMRI and preoperative patient characteristics with BCR. Results: Of 365 patients who had RARP, 21 met criteria for BCR with a median follow up of 19 months (IQR: 10-34). Mean preoperative PSA (ng/mL) [p<0.001], high MRI suspicion level [p=0.016], presence of extracapsular extension (ECE) on MRI [p=0.003], and total prostate volume by MRI (cc) [p<0.001] were associated with BCR. Increasing MRI suspicion corresponded to increases in rates of BCR within suspicion levels (2.22% of low, 3.88% of moderate, and 10.64% of high). The rates of BCR were significantly greater in men with ECE on final pathology [p<0.001]. Gleason grade trended toward significance [p=0.058]. Controlling for potentially confounding preoperative variables on multivariate analysis, MRI suspicion score, ECE on MRI, and total prostate volume by MRI remained significantly associated with predicting BCR. Conclusions: MRI suspicion score, ECE on mpMRI, and total prostate volume were associated with BCR in patients undergoing RARP. Preoperative mpMRI characteristics aid in risk stratification, patient counseling, and modification of surgical technique in those with high risk imaging features for BCR. The integration of mpMRI characteristics into a comprehensive model of BCR may provide robust tools for preoperative staging and surgical planning.

Abstract BACKGROUND Scoliosis X-rays are the gold standard for assessing preoperative lumbar lordosis; however, particularly for flexible lumbar deformities, it is difficult to predict from these images the extent of correction required, as standing radiographs cannot predict the thoracolumbar alignment after intraoperative positioning. OBJECTIVE To determine the utility of preoperative MRI in surgical planning for patients with flexible sagittal imbalance. METHODS We identified 138 patients with sagittal imbalance. Radiographic parameters including pelvic incidence and lumbar lordosis were obtained from images preoperatively. RESULTS The mean difference was 2.9° between the lumbar lordosis measured on supine MRI as compared to the intraoperative X-rays, as opposed to 5.53° between standing X-rays and intraoperative X-ray. In patients with flexible deformities (n = 24), the lumbar lordosis on MRI measured a discrepancy of 3.08°, as compared to a discrepancy of 11.46° when measured with standing X-ray. CONCLUSION MRI adequately determined which sagittal deformities were flexible. Furthermore, with flexible sagittal deformities, lumbar lordosis measured on MRI more accurately predicted the intraoperative lumbar lordosis than that measured on standing X-ray. The ability to preoperatively predict intraoperative lumbar lordosis with positioning helps with surgical planning and patient counseling regarding expectations and risks of surgery.

Infiltrating Endometriosis

Endometriosis is a benign gynecologic disease characterized by the presence of endometrial tissue outside the uterine cavity. The complexity of the disease results from its multiple clinical presentations, the multifocal pattern of distribution of the lesions, the presence of extra pelvic sites of the disease (mainly affecting the urinary and the intestinal tracts), and the difficulty in the preoperative diagnosis (by means of imaging studies) and in the surgical treatment. The preoperative mapping of the lesions, either by ultrasound or by magnetic resonance imaging, allows for an adequate surgical planning and a better preoperative patient counseling, especially in those women with deep infiltrating endometriosis affecting the bowel. Also, the choice of the surgical team that is going to perform the procedure may be based on the preoperative workup. In this paper, we highlight the important findings that should be described in the imaging examination reports for the preoperative workup of patients with deep infiltrating endometriosis of the intestine.

Measured Volume

Volume measurment of the breast allows for better surgical planning and implant selection in breast reconstructive and symmetrization procedures. The safety and accuracy of tumor removal, in accordance with oncoplastic principles, may be imporved by knowing the true breast- and breast tumor volume. The authors discuss the methods of volume measurement of the breast and describe the method based on magnetic resonance imaging digital volume measurment in details. The volume of the breast parenchyma and the tumor was determined by processing the diagnostic magnetic resonance scans, and the difference in the volume of the two breasts was measured. Surgery was planned and implant selection was made based on the measured volume details. The authors conclude that digital volume measurement proved to be a valuable tool in preoperative planning of volume reducing mammaplasty, replacement of unknown size implants and in cases when breast asymmetry is treated.
