Clin Radiol 2019 Feb 18. Epub 2019 Feb 18.

Department of Radiology, University Hospitals of Morecambe Bay NHS Trust, Royal Lancaster Infirmary, Ashton Road, Lancaster, LA1 4RP, UK.

Aim: To identify the incidence of spinal-only changes (including both acute inflammatory and chronic structural changes) in patients with suspected spondyloarthropathy (SpA) to determine whether MRI of the sacroiliac joints would be sufficient in the initial radiological work-up and whether the number of spinal magnetic resonance imaging (MRI) examinations performed could be reduced.

Materials And Methods: This was a retrospective study of patients with suspected SpA referred from the rheumatology department of a university teaching hospital undergoing MRI both of the whole spine and of the sacroiliac joints over a 3-year period. Imaging was assessed for the presence of acute inflammatory and chronic structural changes. Read More

Hepatic alveolar hydatid disease (Echinococcus multilocularis), a mimic of liver malignancy: a review for the radiologist in non-endemic areas.

Clin Radiol 2019 Feb 9. Epub 2019 Feb 9.

Department of Imaging, University College London Hospital (UCLH) NHS Trust, London, UK.

Alveolar hydatid disease or alveolar echinococcosis (AE) is caused by the parasite Echinococcus multilocularis and is increasingly seen as an imported disease in non-endemic areas such as the UK. It is rare compared to cystic echinococcosis (CE), but like CE commonly affects the liver. AE does have imaging features that can aid in diagnosis, but is often initially misdiagnosed as liver malignancy. Read More

Clin Radiol 2019 Mar 23;74(3):242-246. Epub 2019 Jan 23.

Department of Radiology, St Thomas' Hospital, Westminster Bridge Road, London SE1 7EH, UK.

Since the inception of the National Institute for Health Research (NIHR) in 2006, the landscape for the delivery of clinical research within the National Health Service (NHS) has been transformed. Clinical radiology has benefitted from funding opportunities for primary imaging research as well as improvements to the supporting research infrastructure to provide imaging for many clinical trials; however, in an increasingly challenging NHS environment, the NIHR and clinical radiology have to evolve an effective working partnership to ensure imaging research is sustainable and will make an impact. A number of initiatives have arisen from discussions between the NIHR, the Royal College of Radiologists (RCR), and stakeholders that will be discussed in this article. Read More

Division of Thoracic Imaging and Intervention, MGH Department of Radiology, Founders House 202, 55 Fruit Street, Boston, MA 02114, USA. Electronic address:

Aim: To determine if pure ground-glass opacities (GGOs) and the subgroup of ground-glass nodules (GGNs) typically demonstrate higher 2-[F]-fluoro-2-deoxy-d-glucose (F-FDG) uptake at positron-emission tomography (PET) when benign than when malignant.

Materials And Methods: Informed consent was waived for this institutional review board (IRB)-approved, Health Insurance Portability and Accountability Act (HIPAA) compliant, retrospective study. A review of all 1,864 combined PET/computed tomography (CT) examinations performed in 2011 on a single system to identify pure GGOs with mean diameter ≥1 cm yielded 166 GGOs. Read More

Clin Radiol 2019 Jan 2. Epub 2019 Jan 2.

Department of Radiology, Addenbrooke's Hospital and University of Cambridge, Cambridge, UK; CamPARI Clinic, Addenbrooke's Hospital and University of Cambridge, Cambridge, UK.

Multiparametric magnetic resonance imaging (MRI) now plays an essential role in prostate cancer diagnosis and management. The increasing use of MRI before biopsy makes obtaining images of the highest quality vital. The European Society of Urogenital Radiology (ESUR) 2012 guidelines and subsequent Prostate Imaging -Reporting Data System (PI-RADS) version 2 recommendations in 2015 address the technical considerations for optimising MRI acquisition; however, the quality of the multiparametric sequences employed depends not only on the hardware and software utilised and scanning parameters selected, but also on patient-related factors, for which current guidance is lacking.

Effectiveness of premedication protocol using intravenous fentanyl to reduce pain associated with femoral artery closure device placement.

Clin Radiol 2019 Feb 24;74(2):166.e9-166.e13. Epub 2018 Dec 24.

University of Illinois and Mercyhealth Rockford, IL, USA.

Aim: To test the effectiveness of a premedication protocol using intravenous bolus of 100 μg fentanyl to reduce pain associated with femoral artery closure device placement for neuro-endovascular procedures.

Materials And Methods: The severity of pain associated with femoral artery closure device placement was analysed using a numerical rating scale score ranging from 0 (no pain) to 10 (most severe pain) in two cohorts of consecutive adult patients (n=118), those who were (n=64) or were not (n=54) treated with premedication protocol. The primary endpoints were the proportion of patients with excellent (score ≤1) and failed pain control (score ≥8). Read More

The value of MR textural analysis in prostate cancer.

Clin Radiol 2018 Dec 17. Epub 2018 Dec 17.

Leeds Institute of Cancer and Pathology, University of Leeds, UK; Department of Radiology, Leeds Teaching Hospitals NHS Trust, UK.

Current diagnosis and treatment stratification of patients with suspected prostate cancer relies on a combination of histological and magnetic resonance imaging (MRI) findings. The aim of this article is to provide a brief overview of prostate pathological grading as well as the relevant aspects of multiparametric (MRI) mpMRI, before indicating the potential that magnetic resonance textural analysis (MRTA) offers within prostate cancer. A review of the evidence base on MRTA in prostate cancer will enable discussion of the utility of this field while also indicating recommendations to future research. Read More

What is the best fruit juice to use as a negative oral contrast agent in magnetic resonance cholangiopancreatography?

Clin Radiol 2019 Mar 13;74(3):220-227. Epub 2018 Dec 13.

Radiology Unit, Department of Diagnostic Medicine and Prevention, S. Orsola Hospital, University of Bologna, Bologna, Italy.

Aim: To identify, in vitro, the best fruit juice to use as oral contrast agent in magnetic resonance cholangiopancreatography (MRCP) and to test, in vivo, the best natural juice and the new parameters in MRCP sequences identified in vitro.

Materials And Methods: The in vitro evaluations consisted of measuring the T2 values of a pure solution of manganese (Mn) and iron (Fe) at different concentrations, measuring the content of Mn and Fe in five commercial juices and their T2 relaxation times, and identifying the optimal juice dilution for suppressing the gastrointestinal fluid signal. The new parameters of MRCP sequences were tested in vivo. Read More

Relationship between F-FDG PET metabolic parameters and MRI intravoxel incoherent motion (IVIM) histogram parameters and their correlations with clinicopathological features of cervical cancer: evidence from integrated PET/MRI.

Clin Radiol 2019 Mar 10;74(3):178-186. Epub 2018 Dec 10.

Department of Radiology, Shengjing Hospital of China Medical University, Sanhao Street No36, Heping District, Shenyang, Liaoning 110004, China.

Aim: To explore the relationship between positron-emission tomography (PET) and intravoxel incoherent motion (IVIM) histogram parameters and their correlations with the clinicopathological features of cervical squamous cell cancer (CSCC).

Texture analysis of cardiovascular magnetic resonance cine images differentiates aetiologies of left ventricular hypertrophy.

Clin Radiol 2019 Feb 24;74(2):140-149. Epub 2018 Oct 24.

Bart's Heart Centre, London, UK; Institute of Cardiovascular Science, University College London, UK.

Aim: To investigate whether unenhanced cardiovascular magnetic resonance (CMR) balanced steady state free precession (bSSFP) cine images could be analysed using textural analysis (TA) software to differentiate different aetiologies of disease causing increased myocardial wall thickness (left ventricular hypertrophy [LVH]) and indicate the severity of myocardial tissue abnormality.

Materials And Methods: A mid short axis unenhanced cine frame of 216 patients comprising 50 cases of hypertrophic cardiomyopathy (HCM; predominantly Left ventricular outflow tract obstruction [LVOTO] subtype), 52 cases of cardiac amyloid (CA; predominantly AL: light chain subtype), 68 cases of aortic stenosis (AS), 15 hypertensive patients with LVH (HTN+LVH), and 31 healthy volunteers (HV) underwent TA of the CMR cine images (CMRTA) using TexRAD (TexRAD Ltd, Cambridge, UK). Among the HV, 16/31 were scanned twice to form a test-retest reproducibility cohort. Read More
