#1
Roohi Jeelani, Elizabeth E Puscheck
Ultrasound (US) has transformed the fertility evaluation. With 1 consultation, blood work and 1 to 2 USs, the female fertility status can be fully evaluated. The initial US is best done early in the follicular cycle to evaluate the pelvic anatomy and ovarian reserve. A three-dimensional US is important to evaluate for uterine anomalies and color Doppler for any masses. A mid-cycle saline infusion sonohysterogram assesses the endometrial cavity better than a hysterosalpingogram as it identifies the cause of any filling defects...

BACKGROUND: The study aimed to compare sex differences in the morphology and spatial orientation of pelvic acetabula to advance the understanding of hip anatomy. MATERIAL AND METHODS: The study was based on three-dimensional reconstructions of computed tomography images of 50 female and 50 male acetabula. The images were used for spatial analysis of hip acetabula relative to the base of the sacral bone as the plane of reference. Statistical analysis was performed to compare angles relevant to the actual axis of the acetabulum (inclination angle, anteversion angle, tilt angle) as well as the volume and inner surface area of the acetabulum...

The preimplantation ultrasound (US) refers to targeted imaging of the uterus and adnexa prior to assisted reproductive techniques (ART) to optimize the infertility treatment outcomes. After a thorough evidence based literature review, we propose the use of transvaginal three-dimensional (3D) US during the early follicular phase. A systematic approach for 3D US examination consists of a detailed examination of the uterine shape, size and contour, evaluation of the endometrial thickness, volume, pattern and vascularity, and assessment of the junctional zone regularity, echogenicity and thickness...

: The greater use of magnetic resonance imaging (MR) in brachytherapy, for both image based planning and image guided procedures, presents a number of challenges for the physicist involved. MR is widely acknowledged as the imaging modality of choice to appreciate a patient's pelvic anatomy and is thus used more often for brachytherapy of gynecologic and prostate cancers. Incorporating MR in brachytherapy treatments requires changes throughout the clinical workflow from implantation through target definition, applicator digitization and post-implant evaluation...

PURPOSE: To make Image Guided Radiation Therapy (IGRT) credentialing a more unified, consistent and efficient process across the entire National Clinical Trial Network (NCTN). METHODS: IGRT plays a role in several advanced NCTN trials. Previously an institution had to be IGRT credentialed for each protocol. When institutions were allowed to use previous credentials for new protocols it was limited to the same disease site as the original credentialing. The credentialing was analyzed by the physics PI of the protocol...

PURPOSE: To investigate the impact of bladder filling status of the organs at risk (OARs) on dose distribution during intensity modulated radiotherapy (IMRT) for cervical cancer patients. METHODS: Twelve cervical cancer patients treated with IMRT were selected for this study. The prescription dose was 45Gy/25 fractions with the 6 MV photon beam. All patients performed two CT scans, one with an empty bladder, the other one with bladder filled. For the registration of two CT scans, the fusion was automatically carried out upon the bony anatomy...

T Cui, Q Shang, W Li, A Vassil, P Xia
PURPOSE: To evaluate a dual-isocentric technique to compensate for the daily independent movements of prostate and pelvic lymph nodes (PLN) of high-risk prostate cancer patients. METHODS: Three patients, who received 78 Gy to the prostate, 66 Gy to the seminal vesicle (SV), and 50.4 Gy to the PLN in 39 fractions under CT-on-rail (CTOR) imaging guidance, were retrospectively selected. Each patient was planned with volumetric modulated arc therapy (VMAT) techniques using (1) single isocenter with a 6 mm margin except 4 mm posteriorly (6/4 mm), to the prostate-CTV and a uniform 5 mm margin to the PLN-CTV, and (2) two isocenters, located at the centroids of the prostate or the PLN, with a 5/3 mm margin to the prostate-CTV and a 5 mm uniform margin to the PLN-CTV...

PURPOSE: When a patient's anatomy spans beyond the scan field of view (sFOV) in a CT scanner, extrapolation techniques are applied to reconstruct data in the extended field of view (eFOV). However, it's challenging to delineate the external body contour accurately due to image distortions within eFOV. Our proposed solution is to apply TargetTape, a disposable radio-opaque adhesive strip, to patients. Our study investigates the accuracy of geometric reconstruction and the dosimetric impact when using TargetTape in eFOV...

PURPOSE: We are conducting a clinical trial on stereotactic body radiation therapy (SBRT) for high-risk prostate cancer. Doses to three targets, prostate, intra-prostatic lesion, and pelvic lymph node (PLN) region, are escalated to three different levels via simultaneous integrated boost technique. Inter-/intra-fractional organ motions deteriorate planned dose distribution. This study aims at developing a dose reconstruction system to comprehensively understand the impacts of organ motion in our clinical trial...

PURPOSE: The use of fiducials markers in prostate treatment allows a precise localization of this volume. Typical prostate SBRT margins with fiducials markers are 5mm in all directions, except toward the rectum, where 3mm is used. For some patients nearby pelvic lymph nodes with 5mm margin need to be irradiate assuming that its localization is linked to the prostate fiducial markers instead of bony anatomy. The purpose of this work was to analyze the geometric impact of locate the lymph node regions through the patient positioning by prostate fiducial markers...

Radical prostatectomy (RP) is the most common cause of stress urinary incontinence (UI) in men. Several anatomic structures affect or may affect urinary continence - urethral sphincter, levator ani muscle, puboprostatic ligaments, bladder neck, endopelvic fascia, neurovascular bundle - and understanding of the anatomy of pelvic floor and urethra is crucial for satisfactory functional outcome of the procedure. Surgical techniques implemented to improve continence rates include nerve-sparing procedure, bladder neck preservation/plication, urethral length preservation, musculofascial reconstruction, puboprostatic ligaments preservation or seminal vesicle preservation...

INTRODUCTION: The increasingly more complex nature of hernia surgery means that training programs for young surgeons must now meet ever more stringent requirements. There is a growing demand for improved structuring and standardization of education and training in hernia surgery. MATERIALS AND METHODS: In 2011, the concept of a Hernia School was developed in Germany and has been gradually implemented ever since. That concept comprises the following series of interrelated, tiered course elements: Hernie kompakt (Hernia compact), Hernie konkret (Hernia concrete), and Hernie complex (Hernia complex)...

PURPOSE: Scoliosis with pelvic obliquity (PO) could be investigated with the EOS-CHAIR protocol as the most common deformity especially in patients with trunk hypotonia and quadriplegia. However, the intra-observer and inter-observer reliability of various angles assessing PO was not investigated with this new imaging protocol. METHODS: A retrospective cohort of 36 EOS frontal full-spine acquisitions made in sitting position was used. The sacroiliac pelvic obliquity angle, iliac crest pelvic obliquity angle, and ischiatic pelvic obliquity angle were assessed in an intra-observer and inter-observer study...
