Purpose Optical stimulated luminescence (OSL) combines reusability, sub-mm resolution, and a linear dose response in a single radiation detection technology. Such a combination is currently lacking in radiotherapy dosimetry. But OSL-films have a strong energy dependent response to keV photons due to a relative high effective atomic number (Zeff). The current work studied the applicability of a 2D OSL-film with a reduced Zeff as (IMRT/VMAT) dosimeter. Methods and Materials Based on their commercial OSL-film experience, Agfa Healthcare N...

This commentary summarizes insights and discussions about the status of women leaders in STEM (science, technology, engineering, and medicine). While many academic institutions now train close to 50 % female students in STEM disciplines, there is a major underrepresentation of qualified women in leadership roles. Women are admitted to the basements of STEM institutions, but only few make it to the top floor. We see male superstars receiving well-deserved recognitions and advancements. Unfortunately, their female counterparts are often held back or cut down by both male and female colleagues...

To advance magnetic resonance imaging (MRI) technologies further for in vivo tissue characterization with histopathologic validation, we investigated the feasibility of ex vivo tissue imaging of a surgically removed human brain tumor as a comprehensive approach for radiology-pathology correlation in histoanatomically identical fashion in a rare case of pigmented ganglioglioma with complex paramagnetic properties. Pieces of surgically removed ganglioglioma, containing melanin and hemosiderin pigments, were imaged with a small bore 7-T MRI scanner to obtain T1-, T2-, and T2*-weighted image and diffusion tensor imaging (DTI)...

REVIEW
Minhao Hu, David Wattchow, Dayan de Fontgalland
The landscape of surgical anatomy education is progressively changing. Traditional methods, such as cadaveric dissection and didacticism are being increasingly phased out in undergraduate courses for multimodal approaches incorporating problem-based learning, radiology and computer-based simulations. Although effective at clinically contextualizing and integrating anatomical information, these approaches may be a poor substitute for fostering a grasp of foundational 'pure' anatomy. Dissection is ideal for this purpose and hence remains the cornerstone of anatomical education...

In 2001 the ACPSEM published a position paper on quality assurance in screen film mammography which was subsequently adopted as a basis for the quality assurance programs of both the Royal Australian and New Zealand College of Radiologists (RANZCR) and of BreastScreen Australia. Since then the clinical implementation of digital mammography has been realised and it has become evident that existing screen-film protocols were not appropriate to assure the required image quality needed for reliable diagnosis or to address the new dose implications resulting from digital technology...

With advances in diagnostic technology, radiologic diagnostic methods have been used more frequently, and physical examination may be neglected. The authors report a case of pediatric medial orbital trapdoor fracture in which the surgery was delayed because computed tomography (CT) findings did not indicate bone displacement, incarceration of rectus muscle, or soft tissue herniation. A healthy 6-year-old boy was admitted to the emergency room for right eyebrow laceration. We could not check eyeball movement or diplopia, because the patient was irritable...

The patient data confidentiality is one of the vital security aspects in e-Health and m-Health services. In particular, providing confidentiality to the patient's medical image is essential and the protection approaches have to be explored in-depth due to the rapid progress in the technologies of teleradiology and PACS. In this study, the pseudo random number generators (PRNGs), namely, the linear congruential generator (LCG) and XOR shift generator (XSG) are improved and combined with improved logistic 2D coupled chaotic map to provide enhanced chaos based encryption...

INTRODUCTION: Chronic recurrent multifocal osteomyelitis (CRMO) is a very rare disease, of unknown origin that affects primarily the metaphysis of long bones. It is characterized by an insidious onset of symptoms and multiple remissions. The chronicity of symptoms, the diagnostic imaging and the lack of response to first line antibiotic treatment, should be helpful for diagnostic. OBJECTIVE: Present a clinical case, based on clinical, laboratory, radiologic imaging and histopathological results, that ultimately led to the diagnostic of CRMO...

REVIEW
Melissa J McGettigan, Robert A Gatenby
Modern technologic advances in medical imaging and the increasing use of imaging across all disciplines in medicine have led to a striking rise in incidental findings unrelated to the original study indication. Often, these findings have no clinical relevance and will not impact the current or future health status of the patient. It is incumbent on radiologists to report these findings in a definitive and unambiguous manner. Similarly, it is essential for clinicians to restrain from further diagnostic investigation of incidental findings that are conclusive by imaging...

OBJECTIVE: One of the most serious complications following subarachnoid hemorrhage (SAH) is delayed cerebral ischemia (DCI) secondary to symptomatic vasospasm. An animal model mimicking post SAH vasospasm is essential for enabling the translation of newer technologies from the conceptual phase to animal studies, and eventually to clinical trials. Various animal models of DCI following SAH have been reported, with canine models being the most common. Due to the similarity of the swine cardiovascular system and its dimensions to the human's system, the main objective of this study was to establish a consistent and quantitatively representative model of SAH-induced vasospasm in swine...

PURPOSE: Lung field segmentation for chest radiography is critical to pulmonary disease diagnosis. In this paper, we propose a new deformable model using weighted sparse shape composition with robust initialization to achieve robust and accurate lung field segmentation. METHODS: Our method consists of three steps: initialization, deformation and regularization. The steps of deformation and regularization are iteratively employed until convergence. First, since a deformable model is sensitive to the initial shape, a robust initialization is obtained by using a novel voting strategy, which allows the reliable patches on the image to vote for each landmark of the initial shape...

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease that lacks effective biomarkers for early detection. We hypothesized that circulating long non-coding RNAs (lncRNAs) may act as diagnostic markers of incidentally-detected cystic PDAC precursors known as intraductal papillary mucinous neoplasms (IPMNs) and predictors of their pathology/histological classification. Using NanoString nCounter® technology, we measured the abundance of 28 candidate lncRNAs in pre-operative plasma from a cohort of pathologically-confirmed IPMN cases of various grades of severity and non-diseased controls...

Interventional radiology (IR) is a fast expanding field which includes vascular (arterial and venous) as well as non-vascular topics. IR is minimally invasive methods, which are performed under guidance of radiological modalities. The methods are in general patient-friendly and organ-sparing procedures and can often be performed on out-patient basis or with short admission to the hospital and with short reconvalescence and economic advantages compared with corresponding surgical treatments. IR has in some cases substituted former surgical procedures...

Hybrid operating rooms (HOR) are rooms that mix interventional radiology and surgical equipments. They are usually used in heart, vascular, orthopedic and neurosurgery, and make it possible to consider new minimally invasive procedures in urology. Thanks to these, we developed a new partial nephrectomy technique without renal pedicle clamping and without ischemia. Renal cancer is now diagnosed at localized stage in most of the cases, and its treatment is mostly based on nephron sparing surgery. However, the hemorrhagic character of this intervention requires a renal pedicle clamping whose long-term consequences on renal function are discussed...

Electrophysiology procedures are traditionally performed under fluoroscopic guidance. Nowadays a growing interest in the radiation risk associated to these procedures has been cultivated, since radiation exposure has non-neglegible stochastic and deterministic effects on health. A correlation between radiation exposure and lifetime malignancy effect is difficult to establish and the threshold of a completely safe exposure dose is unknown. Thus, electrophisiologists have become aware of the use of fluoroscopy and they have tried to use all the complementary imaging technologies available in order to reduce the radiological exposure...

Queues in hospitals are directly affecting the quality of human life, which should have priority compared to other types of queues. The aim of this paper is to design a future value stream map of the system and patient pathway in terms of quality improvement in order to decrease the non-value added activities for breast cancer patients, doctors and nurses for a radiology unit in a Training and Research University Hospital based in Kocaeli, Turkey. Nowadays, the increased demand versus insufficient sources affect healthcare services due to poor quality with long queues during the diagnosis and treatment processes...
