Transperineal permanent brachytherapy is a safe and effective treatment option for patients with organ-confined prostate cancer. Careful adherence to established brachytherapy standards has been shown to improve the likelihood of procedural success and reduce the incidence of treatment-related morbidity. A collaborative effort of the American College of Radiology (ACR) and the American Brachytherapy Society (ABS) has produced practice parameters for LDR prostate brachytherapy. These practice parameters define the qualifications and responsibilities of all the involved personnel, including the radiation oncologist, physicist and dosimetrist...

Bleeding in the upper gastrointestinal (GI) tract is a frequent and complex emergency. There are guidelines for acute medical treatment, established endoscopic treatment as well as surgical and radiological rescue procedures. Nevertheless, the mortality of the upper GI tract bleeding is high, which is due to the fact that affected patients often have serious preexisting illnesses.

Neuroendocrine tumours (NET) are rare neoplasms, but the incidence is permanently increasing. Most of the NETs are slow proliferating and clinically silent, and for that reason, they are often diagnosed at a stage with advanced disease. The complexity and diversity of the NET-biology require the treatment of patients in specialised centres to guarantee a qualified, multidisciplinary treatment planning. At our institution, we developed an interdisciplinary model for the assessment and treatment of NET. The aim was to adapt the guidelines to the clinical practice, exchange of current knowledge, and a tailored approach to the individual patient...

INTRODUCTION: Spontaneous pneumothorax in pediatric patients is relatively uncommon. The management strategy varies in different centers due to dearth of evidence-based pediatric guidelines. In this study, we reviewed our experience of thoracoscopic management of primary spontaneous pneumothorax (PSP) in children and identified risk factors associated with postoperative air leakage and recurrence. MATERIALS AND METHODS: We performed a retrospective analysis of pediatric patients who had PSP and underwent surgical management in our institution between April 2008 and March 2015...

PURPOSE: To determine the efficacy and safety of percutaneous omental biopsy. METHODS: Retrospective review was performed of all 181 percutaneous omental biopsies performed at a single institution between 9/18/2002 and 2/12/2016. Mean patient age was 67 (±14) years, and 114 (63%) patients were female. Biopsy results were compared to subsequent surgical pathology and paracentesis cytology, when available, and cases were further evaluated based on the imaging appearance of the omental abnormality...

Core needle biopsy (CNB) has been suggested as a complementary diagnostic method to fine-needle aspiration in patients with thyroid nodules. Many recent CNB studies have suggested a more advanced role for CNB, but there are still no guidelines on its use. Therefore, the Task Force Committee of the Korean Society of Thyroid Radiology has developed the present consensus statement and recommendations for the role of CNB in the diagnosis of thyroid nodules. These recommendations are based on evidence from the current literature and expert consensus...

This paper is a summary of the methodology including protocol used to develop evidence-based clinical imaging guidelines (CIGs) in Korea, led by the Korean Society of Radiology and the National Evidence-based Healthcare Collaborating Agency. This is the first protocol to reflect the process of developing diagnostic guidelines in Korea. The development protocol is largely divided into the following sections: set-up, process of adaptation, and finalization. The working group is composed of clinical imaging experts, and the developmental committee is composed of multidisciplinary experts to validate the methodology...

The histologic changes occurring in severe/therapy-resistant asthma (SA) as defined by the European Respiratory Society/American Thoracic Society guidelines, particularly at the level of the distal airways are unknown. This study describes the clinical, radiologic, and histologic characteristics of 29 SA patients who underwent video-assisted thoracoscopic surgery lung biopsy. Pathologic observations were correlated with clinical features, especially the presence of autoimmune disease (AID) (15/29, 51.7%). Ten biopsies (10/29, 34...

OBJECTIVES: To assess the feasibility, image quality, and accuracy of freehand biopsies of liver, bone, muscle, vertebral disc, soft tissue, and other lesions using balanced steady-state free precession (SSFP, balanced fast field echo: bFFE), spoiled and nonspoiled gradient echo (FFE), and turbo spin echo (TSE) sequences for interactive continuous navigation in an open magnetic resonance imaging (MRI) system at 1.0 tesla (T). METHODS: Twenty-six MR-guided biopsies (five liver, five bone, four muscle, four vertebral disc, one lung, one kidney, one suprarenal gland, and five soft or other tissue) were performed in 23 patients in a 1...

BACKGROUND: A spontaneous renal artery dissection is a very rare diagnosis. The clinical presentation can vary and its course can be atypical. There are no guidelines available regarding treatment; however, the options are a conservative (medication) or interventional (radiological or surgical) approach. CASE DESCRIPTION: A 45-year-old man presented to the emergency department with hypertensive urgency after earlier episodes of flank pain. The cause appeared to be a spontaneous bilateral renal artery dissection with infarction...

Diagnosis of Cushing's syndrome (CS) and identification of the aetiology of hypercortisolism can be challenging. The Endocrine Society clinical practice guidelines recommends one of the four tests for initial screening of CS, namely, urinary-free cortisol, late night salivary cortisol, overnight dexamethasone suppression test or a longer low-dose dexamethasone suppression test, for 48 hours. Confirmation and localisation of CS requires additional biochemical and radiological tests. Radiological evaluation involves different imaging modalities including MRI with or without different radio-nuclear imaging techniques...

REVIEW
D R Aberle
The reduced lung cancer mortality observed with low-dose computed tomography (LDCT) screening in the National Lung Screening Trial (NLST) has led to annual screening in the United States as a covered benefit by both private insurers and the federal health insurance programme, the Centers for Medicare and Medicaid Services. Reimbursement for screening requires data submission to a federal registry on all individuals, whether privately or federally insured. Data must document individual patient eligibility as well as shared decision-making regarding the benefits and risks of LDCT screening, smoking cessation counselling, and the importance of annual screening...

BACKGROUND AND PURPOSE: Evans index is an estimate of ventricular size used in the diagnosis of idiopathic normal-pressure hydrocephalus (iNPH). Values >0.3 are considered pathological and are required by guidelines for the diagnosis of iNPH. However, there are no previous epidemiological studies on Evans index, and normal values in adults are thus not precisely known. We examined a representative sample to obtain reference values and descriptive data on Evans index. METHODS: A population-based sample (n = 1235) of men and women aged ≥70 years was examined...

Given dozens of competing journals accepting medical physics articles, it may not be clear to an individual author which journal is the best venue for disseminating their work to the scientific community. Relevant factors usually include the Journal's audience and scientific impact, but also such factors as perceived acceptance rate, interest in their topic, and quality of service...

PURPOSE: To accommodate head-and-neck (HN) RT simulation scan with immobilization, sub-optimized flexible radiofrequency coils have to be used on an MR-sim rather than a volumetric head coil for diagnostic radiological (DR) applications. In this study, we present and compare ACR MRI phantom test with flexible coils setting (RT-setting) and volumetric head coil setting (DR-setting). METHODS: Two 8-channel array coils were wrapped close to an ACR MRI phantom placed on a flat couch-top in RT-setting for acquisition...

PURPOSE: To develop and demonstrate a short breast (sb) MRI protocol that acquires both T2-weighted and dynamic contrast-enhanced T1-weighted images in approximately ten minutes. METHODS: The sb-MRI protocol consists of two novel pulse sequences. The first is a flexible fast spin-echo triple-echo Dixon (FTED) sequence for high-resolution fat-suppressed T2-weighted imaging, and the second is a 3D fast dual-echo spoiled gradient sequence (FLEX) for volumetric fat-suppressed T1-weighted imaging before and post contrast agent injection...
