In a paper in this issue of Diabetologia (DOI: https://doi.org/10.1007/s00125-017-4417-x ), Vouillarmet and colleagues have explored the use of single-photon emission computed tomography (SPECT)/computed tomography (CT) to define remission during non-surgical management of osteomyelitis of the foot. Their experience in a non-controlled observational study of 45 individuals was that a negative white blood cell-SPECT/CT scan is a reliable marker of remission, while a positive scan at the end of antibiotic treatment may be relatively useful in the prediction of future short- to medium-term relapse...

BACKGROUND: Failed back surgery syndrome (FBSS) has a high incidence following spinal surgery, is notoriously refractory to treatment, and results in high health care utilization. Spinal cord stimulation (SCS) is a well-accepted modality for pain relief in this population; however, until recently magnetic resonance imaging (MRI) was prohibited due to risk of heat conduction through the device. OBJECTIVES: We examined trends in imaging use over the past decade in patients with FBSS to determine its impact on health care utilization and implications for patients receiving SCS...

INTRODUCTION: Understanding the real shape of the undersurface of the acromion prior to acromioplasty is indispensable. Today, Supraspinatus outlet view (SSOV) is a standard view used to determine the shape of the anterior acromion. Three types of acromial undersurface were described by Bigliani and Morrison. The purpose of this study was to find out whether the real acromial type can be visualized on X-ray SSOV and compare the shape of the anterior undersurface of the acromion visualized on SSOV, with the shape revealed on 2D CT reconstructions...

Trauma is one of the leading causes of death for men and women under the age of 45 years old, and abdominal injuries contribute to a large number of these deaths. Prompt diagnosis is very important for treatment decision making and can be life-saving. CT has become an essential imaging modality in emergency medicine. In this pictorial review, we present our experience of CT in blunt abdominal trauma and describe CT findings of common injuries, including hemoperitoneum, solid viscera, hollow viscera, mesenteric and diaphragmatic injuries...

Blunt injuries to the chest wall are an important chapter on emergency room (ER) departments, being the third most common injuries in trauma patients which ominous complications could appear. This article describes different types of traumatic events affecting the chest wall, which maybe misdiagnosed with conventional X-ray. Special emphasis has been done in computed tomography (CT) and multidetector CT (MDCT) imaging. This technique is considered the "gold-standard" for those traumatic patients, due to its fast acquisition covering the whole area of interest in axial plane, reconstructing multiplanar (2D, 3D) volume-rendered images with a superb quality and angiographic CT capabilities for evaluating vascular damage...

PURPOSE: CT during hepatic arteriography (CTHA) of cone-beam computed tomography (CBCT) provides valid information in performing transcatheter arterial chemo-embolization (TACE). The usefulness of CTHA with the diluted contrast medium has been reported in some medical conferences. However, the operation becomes somehow complicated for the medical institutions that have angiography injectors with a single head. In this study, we aimed to investigate the clinical equivalence of low-rate injection method and diluted injection method...

RATIONALE: Pancreatic acinar cell carcinoma (ACC) is a rare malignant tumor of exocrine pancreas. It is typically a well-marginated large solid mass arising in a certain aspect of the pancreas. Diffuse involvement of ACC in the pancreas is very rare, and may simulate pancreatitis in radiological findings. We report 2 cases of ACC presenting as diffuse enlargement of the pancreas due to tumor involvement without formation of a distinct mass. PATIENT CONCERNS: The patients consisted of a 41-year-old man with weight loss and a 77-year-old man who was asymptomatic...

Objectives Low-dose computed tomography lung cancer screening has been shown to reduce lung cancer mortality but has a high false-positive rate. The precision medicine approach to low-dose computed tomography screening assesses subjects' benefits versus harms based on their personal lung cancer risk, where harms include false-positive screens and resultant invasive procedures. We assess the relationship between lung cancer risk and the rate of false-positive LDCT screens. Methods The National Lung Screening Trial randomized high-risk subjects to three annual screens with low-dose computed tomography or chest radiographs...
