Sidharth Sharma, Christopher D Lucas
OBJECTIVES: Pulmonary embolism (PE) is a frequently suspected life-threatening condition that often presents with non-specific signs and symptoms. There is concern that increased availability of computerized tomography pulmonary angiogram (CTPA) is resulting in overuse in the diagnostic workup of patients presenting with cardio-respiratory symptoms. We therefore aimed to determine whether use of CTPA was increasing over time within our institution, with a consequent decrease in the diagnostic yield of PE...

OBJECTIVES: To establish a system for patient dosimetry audit and setting of Local Diagnostic Reference Levels (LDRLs) for Nuclear Medicine (NM) CT. METHODS: Computed Radiological Information System (CRIS) data were matched with NM paper records which provided the body region and dose mode for NMCT carried out at a large UK hospital. It was necessary to divide data in terms of the NM examination type, body region and dose mode. The mean and standard deviation Dose Length Products (DLPs) for common NMCT examinations were then calculated and compared to the proposed National DRLs (NDRLs)...

REVIEW
Marc S Levine, Stephen E Rubesin
This article reviews the history of the barium swallow from its early role in radiology to its current status as an important diagnostic test in modern radiology practice. Though a variety of diagnostic procedures can be performed to evaluate patients with dysphagia or other pharyngeal or esophageal symptoms, the barium study has evolved into a readily available, non-invasive, and cost-effective technique that can facilitate the selection of additional diagnostic tests and guide decisions about medical, endoscopic, or surgical management...

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...

INTRODUCTION: Non-tuberculous mycobacteria (NTM) can cause disease which can be clinically and radiologically undistinguishable from tuberculosis (TB), posing a diagnostic and therapeutic challenge in high TB settings. We aim to describe the prevalence of NTM isolation and its clinical characteristics in children from rural Mozambique. METHODS: This study was part of a community TB incidence study in children <3 years of age. Gastric aspirate and induced sputum sampling were performed in all presumptive TB cases and processed for smear testing using fluorochrome staining and LED Microscopy, liquid and solid culture, and molecular identification by GenoType® Mycobacterium CM/AS assays...

Patients with obstructive sleep apnea (OSA) in long-term treatment with a mandibular advancement device (MAD) to increase the upper airway space, may develop changes in the temporomandibular joint (TMJ) and the orofacial function due to the protruded jaw position during sleep. The aim was to investigate the influence of long-term MAD treatment on the TMJs, orofacial function and occlusion. This prospective study included 30 men and 13 women (median age 54) with OSA (Apnoea-Hypopnoea Index (AHI): 7-57). They were examined with the Nordic Orofacial Test Screening (NOT-S), the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and cone beam computed tomography (CBCT) of the TMJs...

Foreign-body (FB) ingestion is less common in adults than in children, but still occurs. Diagnostic management of patients with suspected FB ingestion in emergency departments depends on FB type and location, both of which are related to the patient profile. In adults, fish and chicken bones are the most common FB types, and the oropharynx and cricopharyngeal muscle are the most common locations. Once accidentally swallowed, an FB may become lodged in the oropharynx, and in such cases indirect or fiberoptic laryngoscopy is the first clinical management option...

Involvement of tendons and tendon sheaths is frequently found in the most common inflammatory systemic diseases, rheumatoid arthritis and spondyloarthritis. In rheumatoid arthritis tendon manifestations occur as tenosynovitis, with swelling and pain of the tendons mainly on the hands and feet. In spondyloarthritis the involvement of tendons presents as enthesitis with pain and swelling directly at the attachment points of tendons to the bony structures and more commonly in the lower extremities. Pathological alterations of tendons can be normally visualized by sonography and only sometimes with magnetic resonance imaging (MRI) or scintigraphy...

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...

BACKGROUND: Image interpretation and translation into written language is an imperfect process. Yet, the radiology report represents the link between radiologist's opinion and patient's images. Increased access to images through remote viewing stations has made direct communication between radiologists and clinicians less commonplace. We are interested in how accurately the descriptive contents within radiology reports convey the feelings of the radiologist to the referring clinician...
