Pineal parenchymal tumors are rare central nervous system tumors that pose diagnostic challenges for surgical pathologists. Due to their paucity, their clinicopathologic features are still being defined. We report an 86-year-old woman with a remote history of breast lobular carcinoma who presented with a 2-month neurologic history that included gait instability, blurry vision, and headaches.

Methods And Materials: Our DL model uses a pair of cine MRI images as input and provides a motion vector field (MVF) as output. The MVF is then applied to align the input images.
Purpose: Vaginal stenosis (VS) is a recognized complication of pelvic and vaginal radiation therapy (RT).
Methods And Materials: A 26-item survey assessing the signs/symptoms, risk factors, diagnosis, prevention, treatment, and impact of VS on women's sexual health was distributed to radiation oncologists. Descriptive statistics were calculated.
Purpose: Visual Care Path (VCP) is a workflow tool within the ARIA 11 Record and Verify System. The purpose of this study was to quantify the impact of VCP implementation on the metrics of efficiency, safety, and staff satisfaction.
Methods And Materials: Our multidisciplinary quality improvement team reviewed the entire process of patient care and constructed VCP modules to chart serial and parallel events from consultation to treatment completion.
Purpose: Mentorship has been identified by medical students, residents, and faculty as an important component of specialty selection and research productivity in radiation oncology. This study quantitatively analyzes the impact of a mentorship program in radiation oncology targeted to medical students at our institution.
Methods And Materials: We performed a retrospective review of 76 current or former medical students who were mentored by faculty radiation oncologists at our institution between 2004 and 2013.
Objective(s): Recommendations for surveillance after stereotactic body radiation therapy (SBRT) for early stage non-small cell lung cancer (NSCLC) are not well defined. Prospective studies evaluating the efficacy of SBRT have used interval posttreatment imaging with computed tomography (CT). We set out to determine whether positron emission tomography (PET) combined with diagnostic chest CT (PET/d-chest) can enhance detection of potentially salvageable recurrence after SBRT.

Methods And Materials: A retrospective review of documented treatment delivery errors from 2003 to 2009 was performed. Following implementation of IGRT in 2007, patients received daily OBI with orthogonal kV X-rays prior to treatment.
