OBJECTIVE: Improvement in regional blood flow has been shown to ameliorate diabetic gastroparesis. We compared the gastric blood supply in diabetic patients with gastroparesis, with that in healthy subjects, by using contrast-enhanced ultrasound (CEUS). METHODS: Thirty healthy subjects and forty patients with diabetic gastroparesis were enrolled. The CEUS parameters of greater curvatures of the antrum (GCOA) and lesser curvatures of antrum (LCOA), including peak intensity (PI) and the area under the curve (AUC), were compared between the two groups...

OBJECTIVE: To compare the diagnostic accuracy of digital tomosynthesis (DTS) to that of chest radiography for the detection of pulmonary nodules by meta-analysis. METHODS: A systematic literature search was performed to identify relevant original studies from January 1, 1976 to August 31, 2016. The quality of included studies was assessed by quality assessment of diagnostic accuracy studies (QUADAS-2). Per-patient data were used to calculate the sensitivity and specificity and per-lesion data were used to calculate the detection rate...

OBJECTIVE: To develop a novel method for rapid myocardial T1 mapping at high spatial resolution. METHODS: The proposed strategy represents a single-shot inversion-recovery (IR) experiment triggered to early diastole during a brief breathhold. The measurement combines an adiabatic inversion pulse with a real-time readout by highly undersampled radial FLASH, iterative image reconstruction and T1 fitting with automatic deletion of systolic frames. The method was implemented on a 3 T MRI system using a GPU-equipped bypass computer for online application...

Stereotactic body radiotherapy (SBRT) is being increasingly utilized in the treatment of prostate cancer. With the advent of high precision radiosurgery systems, it is possible to obtain dose distributions akin to High Dose Rate (HDR) brachytherapy with SBRT. However, urethral toxicity has a significant impact on the quality of life in prostate cancer patients. Contouring the male urethra on a computed tomography scan is difficult in the absence of an indwelling catheter. In this pictorial essay, we have used the magnetic resonance imaging obtained for radiotherapy planning to aid in delineation of the male urethra and have attempted to define guidelines for the same...

OBJECTIVES: The aim of this feasibility study is to define the resource effectiveness of Cetuximab versus cisplatin given concomitantly with radiotherapy for squamous cell carcinoma within a NHS clinical oncology unit. METHODS: 20 Patients with stage 3 or 4 head and neck squamous cell cancers were randomised to receive either Cetuximab with radiotherapy (ERT) or cisplatin with radiotherapy (CRT) concurrent with external beam radiotherapy 70 Gy in 35 fractions on a 1:1 basis over a 12-month duration...

Ventriculomegaly (VM) is a nonspecific finding on fetal imaging. Identification of the specific etiology is important as it affects prognosis and may even change the course of current or future pregnancies. In this review we will focus on the application of fetal MRI to demonstrate intracranial hemorrhage (ICH) and ischemic brain injury as opposed to other causes of VM. MRI is able to identify the specific etiology of ventriculomegaly with much more sensitivity and specificity than ultrasound and should be considered whenever VM is identified on obstetric ultrasound...

OBJECTIVES: The purpose of this retrospective study was to monitor hypertrophy of the future liver remnant (FLR) following portal vein embolization (PVE) before planned extended right hepatectomy (ERH). However, because individual responses to PVE are highly variable, our focus was to identify co-factors of successful hypertrophy. METHODS: 28 patients with primary or secondary liver tumors, mean age 64.1±12.9 years, underwent PVE. Volumetric analysis of hypertrophy before and after PVE (median 39...

OBJECTIVES: To assess the status and practice of kilovoltage (kV) radiotherapy in the UK. METHODS: 96% of the radiotherapy centres in the UK responded to a comprehensive survey. An analysis of the installed equipment base, patient numbers, clinical treatment sites, quality control (QC) testing and radiation dosimetry processes were undertaken. RESULTS: 73% of UK centres have at least one kV treatment unit, with 58 units installed across the UK...

OBJECTIVES: To evaluate a template-based matching algorithm on single energy (SE) and dual energy (DE) radiographs for markerless localization of lung tumors. METHODS: A total of 74 images from 17 patients with Stage IA-IV lung cancer were considered. At the time of radiotherapy treatment, gated end-expiration SE radiographs were obtained at 60 and 120 kVp at different gantry angles (33 anterior, 41 oblique), from which, soft-tissue enhanced DE images were created...

After a brief history of the major evolutions of PET since its introduction in 1972, this paper reviews the recent improvements and novel trends in PET with a special focus on time of flight that is currently the major research topic. Novel emerging acquisition modalities, such as dual tracer acquisition, inline hadron therapy dose imaging and yttrium-90 imaging are reviewed.

OBJECTIVE: To characterize biliary abnormalities seen in portal cavernoma cholangiopathy (PCC) on Magnetic Resonance Cholangiopancreaticography(MRCP) and elucidate certain salient features of the disease by collaborating our findings with those of previous studies. METHODS: We prospectively enrolled 52 patients with portal cavernoma secondary to idiopathic Extrahepatic portal vein obstruction(EHPVO) who underwent a standard MRCP protocol. Images were analysed for abnormalities involving the entire biliary tree...

OBJECTIVES: Defaecatory MRI allows multicompartmental assessment of defaecatory dysfunction but is often inaccessible. Integrated total pelvic floor ultrasound (transperineal, transvaginal, endoanal) may provide a cheap, portable alternative. Accuracy of total pelvic floor ultrasound for anatomical abnormalities when compared to defaecatory MRI was assessed. METHODS: The dynamic images from 68 women who had undergone integrated total pelvic floor ultrasound and defaecatory MRI between 2009 and 2015 were blindly reviewed...

OBJECTIVES: To prospectively assess the role of whole-lesion apparent diffusion coefficient (ADC) metrics in the characterization of breast tumors by comparing ADC value with ADC entropy. METHODS: 49 patients with 53 breast lesions underwent phased-array breast coil 1.5T-magnetic resonance imaging (MRI). Two experienced radiologists on breast MRI, blinded to the final diagnosis, reviewed the ADC maps and placed a volume-of-interest (VOI) on all slices including each lesion on the ADC map to obtain whole-lesion mean ADC value and ADC entropy...

OBJECTIVES: The purpose of this UK study was to evaluate inter-fraction reproducibility and body image score when using Ultraviolet (UV) tattoos (not visible in ambient lighting) for external references during breast/chest wall radiotherapy and compare to conventional dark ink. METHODS: In this non-blinded, single centre, parallel group, randomised control trial, patients were allocated 1:1 to receive either conventional dark ink or UV ink tattoos using computer generated random blocks...

OBJECTIVES: The purpose of this study is to make a prognostic model for regional relapse in head and neck cancer using clinical and Computed Tomography (CT) parameters. METHODS: 183 patients with lymph node-positive head and neck cancer were treated between 2002 and 2012 with radiotherapy or concurrent chemoradiotherapy. CT studies pre- and post-treatment were reviewed for lymph node size and presence of necrosis, extracapsular spread and calcifications. For every patient, correlations with 3 year regional control (RC), metastasis free survival (MFS), disease free survival (DFS) and overall survival (OS) were made...

OBJECTIVES: We investigated the impact of deep inspiration breath-hold (DIBH) and tumour baseline shifts on image quality and registration uncertainty in image guided DIBH radiotherapy for locally advanced lung cancer. METHODS: Patients treated with daily cone beam CT (CBCT) guided free-breathing (FB) radiotherapy had an additional CBCT in DIBH at three fractions. These CBCTs were off-line rigidly registered (on tumour) to FB and DIBH CTs acquired at planning. All registrations were repeated to evaluate the intra-observer uncertainty...

OBJECTIVE: To compare the dose distributions of intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) using the simultaneous integrated boost (SIB) technique to that of the traditional midline-block (MB) technique for boosting the parametrium in patients with cervical cancer. METHODS: Treatment plans using VMAT or IMRT with the SIB technique (VMAT-SIB and IMRT-SIB) and IMRT followed by the MB technique (IMRT-MB) were generated for each of 10 cervical cancer patients...
