T Jiang, J H Xu, Y Zou, R Chen, L R Peng, Z D Zhou, M Yang
AIM: To evaluate the application of qualitative and quantitative diffusion-weighted imaging (DWI) in predicting the histological grade of hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Two hundred and fifty-four patients with pathologically confirmed HCC who underwent hepatic DWI on a 1.5-T platform (b = 0, 600 s/mm(2)) were evaluated retrospectively. HCCs were divided into well-, moderately, and poorly differentiated groups. The relationships between naked-eye signal intensity (SI), SI values, apparent diffusion coefficient (ADC) values on DWI, and the histopathological differentiation of HCC were analysed...

AIM: To compare the detection rate of extra-regional metastases in patients with recurrent gynaecological malignancies being considered for radical salvage surgery with combined 2-[(18)F]-fluoro-2-deoxy-d-glucose ((18)F-FDG) positron-emission tomography (PET)/computed tomography (CT) compared to conventional imaging. MATERIALS AND METHODS: A retrospective review was performed of all patients in a provincial database with recurrent gynaecological malignancies being considered for pelvic exenteration that underwent restaging with CT/PET between March 2011 and October 2014...

AIM: To evaluate if pre- and post-procedure administration of controlled-release oxycodone (CRO) in combination with standard analgesia improves pain control and decreases the amount of required post-procedure opioids in uterine fibroid embolisation (UFE). MATERIALS AND METHODS: Between January 2009 and March 2010, 60 consecutive women were prospectively randomised in two groups for UFE: the control group, in which 30 patients underwent the standard anaesthetic procedure and the CRO group, in which 30 patients underwent the standard anaesthetic procedure with the addition of CRO...

AIM: To identify whether increased numbers of brainstem lesions are found in the presence of a post-traumatic pupillary function disturbance and classify them anatomically. MATERIALS AND METHODS: In this study, a diagnostic magnetic resonance imaging (MRI) examination was performed within 8 days after traumatic brain injury (TBI) in patients who had been unconscious for more than 24 hours post-TBI. The Glasgow Outcome Scale was evaluated 6 months after TBI. The data obtained from 140 consecutively enrolled patients between 2005 and 2011 were analysed...

AIM: To determine the breast cancer detection rate at routine bilateral screening mammography in women aged 35-39 years attending a symptomatic breast clinic, in women of population-risk profile with a normal clinical examination. METHODS AND MATERIALS: A retrospective analysis of all mammograms performed on patients aged 35-39 years at St James's Hospital from 2011-2015 was carried out. Patients with moderate or high familial risk of breast cancer, personal breast cancer history or chest radiation, males, general practitioner (GP) and internal hospital referrals, and those with abnormal clinical examinations were excluded...

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...

AIM: To investigate changes in myocardial tissue volume during the cardiac cycle to verify the hypothesis of non-compressibility of the myocardium in healthy individuals (HI) as well as in patients with hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), and aortic stenosis (AS). MATERIALS AND METHODS: The study group included 30 HI, and patients with HCM (n=110), DCM (n=89), and AS (n=78). Left ventricular (LV) function, end-diastolic, and end-systolic volumes were calculated based on cardiac magnetic resonance imaging (CMR) for all participants...

AIM: To outline the pathophysiology, clinical presentation, imaging features, and relevant investigations of the different subtypes of breast tuberculosis (TB). MATERIALS AND METHODS: A review was undertaken of all cases (33 in total) of breast TB presenting to Barts Health NHS Trust within a 10-year period, including patient demographics, imaging features, and route of diagnosis. RESULTS: Thirty-three cases of proven granulomatous TB of the breast were identified (11 mastitis obliterans, 10 nodular caseous form, five sclerosing form, four disseminated disease, and three abnormal axillary lymph nodes)...

REVIEW

Hand and wrist infections can present with a spectrum of manifestations ranging from cellulitis to deep-space collections. The various infectious processes can be categorised as superficial or deep infections based on their respective locations relative to the tendons. Superficial hand infections are located superficial to the tendons and are comprised of cellulitis, lymphangitis, paronychia, pulp-space infections, herpetic whitlow, and include volar as well as dorsal subcutaneous abscesses. Deep hand infections are located deep to the tendon sheaths and include synovial space infections, such as infectious tenosynovitis, deep fascial space infections, septic arthritis, necrotising fasciitis, and osteomyelitis...

AIM: To investigate the value of dedicated computed tomography (CT) iterative metal artefact reduction (iMAR) algorithms in patients after spinal instrumentation. MATERIALS AND METHODS: Post-surgical spinal CT images of 24 patients performed between March 2015 and July 2016 were retrospectively included. Images were reconstructed with standard weighted filtered back projection (WFBP) and with two dedicated iMAR algorithms (iMAR-Algo1, adjusted to spinal instrumentations and iMAR-Algo2, adjusted to large metallic hip implants) using a medium smooth kernel (B30f) and a sharp kernel (B70f)...

REVIEW
M Paddock, A Sprigg, A C Offiah
Recognising the skeletal manifestations of inflicted injury (II) in infants and young children is of crucial importance. There are specific fracture patterns which are highly suspicious of II in addition to common differential diagnoses with which radiologists should be familiar. Our objective is to provide a non-exhaustive review of the important factors relevant to the imaging and reporting of II as a platform for further learning. Part 1 encompasses important initial considerations and fracture patterns of the appendicular skeleton...

AIM: To review the radiology-led ultrasound (US) surveillance programme for the detection of hepatocellular carcinoma (HCC) in cirrhotic patients in a UK tertiary-referral centre. MATERIALS AND METHODS: The radiology information system was searched for patients who had undergone US for surveillance of cirrhosis from September 2009 to May 2013. Patient demographics and cirrhosis aetiology were documented. Data including numbers of surveillance scans, abnormal findings suspicious for HCC, subsequent radiological investigations, numbers of HCC and survival for HCC patients were recorded...
