AIM: To investigate the potential role of an additional magnetic resonance imaging (MRI) examination performed during neoadjuvant chemoradiation therapy (CRT) in the prediction of pathological response in locally advanced rectal cancer (LARC). MATERIAL AND METHODS: Forty-eight consecutive patients with LARC underwent neoadjuvant CRT. MRI studies at 1.5 T, including high-resolution T2-weighted sequences that were acquired parallel and perpendicular to the main axis of the tumour were performed before (preMRI), during (midMRI), and 6-8 weeks after the end of CRT (postMRI)...

AIM: To evaluate microstructural visual pathway damage in patients with primary glaucoma (PG) by using 3 T diffusion kurtosis imaging (DKI). MATERIALS AND METHODS: The study was approved by the ethics committee, and all participants provided written informed consent. Ten patients with PG were examined. Twenty healthy individuals served as control subjects. DKI was performed with a GE Silent 3 T magnetic resonance imaging (MRI) unit. Mean diffusivity (MD), fractional anisotropy (FA), and mean kurtosis (MK) maps were automatically created...

AIM: To assess the influence of time, intensity, and trainee seniority on radiology registrars' major and minor discrepancy rates during weekend reporting at a university teaching hospital. MATERIALS AND METHODS: A 12-month retrospective review was performed of out-of-hours trainee provisional reports for computed tomography (CT) and magnetic resonance imaging (MRI) in a university teaching hospital. From Friday 9.00 pm to Sunday 9.00 pm, the out-of-hours service is provided by a single registrar rotating every 12 hours...

AIM: To determine the diagnostic potential of transluminal attenuation gradients (TAG) with exclusion of stented coronary segments (TAG-ExS) and TAG-corrected contrast opacification (CCO) excluding stented coronary segments (TAG-CCO-ExS) for the assessment of in-stent restenosis (ISR). MATERIALS AND METHODS: TAG-ExS and TAG-CCO-ExS were calculated in 93 coronary arteries with 190 stents. The diagnostic performances and the incremental values of the two metrics to coronary computed tomography angiography (CCTA) were analysed and compared...

AIM: To compare computed tomography (CT) radiogenomic and clinical characteristics between patients with epidermal growth factor receptor (EGFR) and Kirsten rat sarcoma viral oncogene (KRAS) mutations in lung adenocarcinomas. MATERIALS AND METHODS: This study was a retrospective analysis of patients with histopathologically confirmed lung adenocarcinoma, who had complete clinical and imaging data, and were tested for EGFR and KRAS mutations. Of the 313 included patients, 116 had effective EGFR mutations (EGFR group), 31 had KRAS mutations (KRAS group), and 166 had no EGFR or KRAS mutations (control group)...

The presence and extent of axillary nodal metastases at the time of breast cancer diagnosis is a critical factor in disease prognosis and plays a central role in deciding the best treatment for patients. Accurate assessment of the axilla is therefore an essential component in staging breast cancer. Over the years, axillary staging has evolved from surgical axillary lymph node dissection (ALND), with its numerous associated long-term complications, to the much less-radical surgical sentinel lymph node excision biopsy (SLNB), the current reference standard...

REVIEW
K Naidoo, S E Pinder
Neoadjuvant therapy is increasingly being recognised as a management option for patients with primary invasive breast carcinoma; this may take the form of primary endocrine treatment or primary chemotherapy. Surgical specimens from women treated with neoadjuvant treatments, particularly primary chemotherapy, may cause a challenge for the histopathologist in handling and interpretation and have, in the past, been sampled, evaluated, and reported in a non-standardised way. This limits comparison between clinical trials and potentially provides clinicians and patients with suboptimal prognostic information...

REVIEW
M J Michell, B Batohi
Digital breast tomosynthesis (DBT) is a modified mammographic technique that overcomes some of the limitations of full-field digital mammography (2DDM) by eliminating the effect of overlapping breast tissue. In the UK, DBT is utilised in both the symptomatic setting and in breast screening assessment clinics. A literature search was conducted from 2010-2017 to ensure that the most recent developments in DBT technology, clinical applications, and assessment of its usefulness in breast screening were reviewed...

AIM: To describe and quantify the range of non-interpretive tasks engaged in by consultant radiologists in Ireland today. MATERIALS AND METHODS: A multiple-choice electronic survey was circulated to over 200 Irish consultant radiologists and results were analysed. RESULTS: Responses were received from approximately 40% of the 267 full-time equivalent consultants in Ireland at the time of the survey. There was a wide sub-specialty mix, and responses from both clinical directors and those without designated administrative responsibility...

AIM: To investigate the value of computed tomography (CT) quantitative parameters in predicting the invasiveness of lung pure ground-glass nodules (pGGNs). MATERIALS AND METHODS: Chest CT images and pathological findings of 163 pGGNs in 154 consecutive patients were reviewed. According to the clinical management strategies, cases were divided into pre-invasive and MIA groups (atypical adenomatous hyperplasia [AAH], adenocarcinoma in situ [AIS], and minimally invasive adenocarcinoma [MIA]) and invasive group (invasive adenocarcinoma [IAC])...

AIM: To compare "selective duodenograms" performed through nasogastric tubes advanced into the proximal duodenum against traditional contrast studies regarding visualisation of a first-pass bolus distention of the duodenum and frequency of inconclusive results. MATERIALS AND METHODS: Retrospective comparison of "selective duodenograms" and traditional upper gastrointestinal contrast studies in neonates with bile-stained vomiting, regarding demonstration of the duodenal C-loop, first-pass bolus capture, degree of distention of the duodenum, and number of inconclusive studies...

REVIEW

The NHS Breast Screening Programme (NHSBSP) was started in 1988 and is a large, organised cancer screening programme. It is delivered by 80 services across England and screens over 2 million women each year. As a screening programme, it must balance the detection of cancers against possible harm to women who do not have cancer. The NHSBSP was therefore designed with detailed information gathering and performance metrics right from the start. In this review paper, we examine how performance metrics in screening mammography have improved the national screening programme and the further developments and challenges that are expected in the years to come...

AIM: To characterise the contrast-enhanced computed tomography (CT) imaging findings of nine patients with intravenous leiomyomatosis (IVL). MATERIALS AND METHODS: The contrast-enhanced CT imaging findings of nine patients with histopathologically proven IVL were examined.

REVIEW
E A Dick, M Ballard, H A Walker, E Kashef, N Batrick, S Hettiaratchy, C G Moran
Blast injuries are complex, severe, and outside of our everyday clinical practice, but every radiologist needs to understand them. By their nature, bomb blasts are unpredictable and affect multiple victims, yet require an immediate, coordinated, and whole-hearted response from all members of the clinical team, including all radiology staff. This article will help you gain the requisite expertise in blast imaging including recognising primary, secondary, and tertiary blast injuries. It will also help you understand the fundamental role that imaging plays during mass casualty attacks and how to avoid radiology becoming a bottleneck to the forward flow of severely injured patients as they are triaged and treated...
