AIM: To explore the value of whole-lesion apparent diffusion coefficient (ADC) first-order statistics and texture features in clinical staging of cervical cancers. MATERIALS AND METHODS: Fifty-six women (mean age, 51 years) with histopathologically confirmed cervical cancers underwent 3 T pelvic magnetic resonance imaging including diffusion-weighted imaging (b=0, 800 s/mm(2)) prospectively. The ADC first-order statistics and texture features derived from the whole volume of cervical cancers were correlated with International Federation of Gynecology and Obstetrics (FIGO) stages (i...

AIM: To compare lesion detectability and positron-emission tomography (PET) metric measurements between early-PET/magnetic resonance imaging (MRI) acquisition and same-day PET/computed tomography (CT). MATERIALS AND METHODS: The study was approved by the institutional review board and written informed consent was obtained from all patients. Twenty-one patients underwent non-time-of-flight (TOF) PET/MRI immediately following (68)GA-prostate-specific membrane antigen (PSMA) tracer injection in two steps: firstly, early prostate PET/MRI (pPET/MRI) and early whole-body (WB) PET/MRI (wbPET/MR) followed by WB TOF PET/CT (wbPET/CT)...

REVIEW
I M Schmalfuss
Sinonasal endoscopy for treatment of benign sinonasal diseases is a well-established procedure. Recent advances in endoscope technology have substantially expanded its application with many institutions now offering resection of skull base lesions and sinonasal malignancies via the endoscopic approach. Its minimally invasive nature leads to faster recovery time, better cosmetic results, and fewer complications. Unfortunately, not all lesions involving the sinonasal region and skull base are accessible to sinonasal endoscopy...

AIM: To assess the rate of upgrade in our screening population to determine whether open excision biopsy of mucocoele-like lesions (MLL) is still required. MATERIALS AND METHODS: A retrospective review of the breast screening database from 1999-2014 was performed. RESULTS: MLL were identified on core biopsy in 113 women (0.6% of those recalled for a core biopsy). The majority (n=100, 88%) had a localised cluster of calcification prompting screening recall...

AIM: To assess the frequency of undetected colon cancer on conventional abdominal CT and to evaluate the imaging features that are characteristic of those cancers. MATERIALS AND METHODS: The present study included consecutive patients diagnosed with colorectal cancer at colonoscopy (2006-2015) who also underwent abdominal computed tomography (CT) performed for various reasons within a year prior to the colonoscopy. The frequency of undetected lesions was evaluated for the original CT interpretations ("original readers")...

AIM: To evaluate the interobserver reproducibility of computed tomography (CT) measurements of maximum tumour diameter and tumour volume for head and neck squamous cell carcinoma. MATERIALS AND METHODS: Eighty consecutive patients who underwent neck CT for the initial evaluation of head and neck squamous cell carcinoma were included in this retrospective study. Two radiologists independently measured the maximal axial diameter and volume of tumours. The reproducibility between the two observers was assessed using 95% Bland-Altman limits of agreement, reproducibility coefficient, within-subject coefficient of variation, and intraclass correlation coefficient with subgroup analysis according to tumour location...

AIM: To evaluate prospectively the performance of combining morphological and arterial spin labelling (ASL) magnetic resonance imaging (MRI) for detecting pseudocapsule defects in renal cell carcinoma (RCC), and to predict renal capsule invasion confirmed histopathologically. MATERIALS AND METHODS: Twenty consecutive patients with suspicious renal tumours underwent MRI. Renal ASL imaging was performed and renal blood flow was measured quantitatively. The diagnostic performance of T2-weighted images alone, and a combination of T2-weighted and ASL images for predicting renal capsule invasion were assessed...

AIM: To evaluate retrospectively the impact of selective arterial embolisation (SAE) on the prognosis of patients with gestational trophoblastic neoplasia (GTN). MATERIALS AND METHODS: A retrospective analysis of the records of all patients with GTN between January 2005 and January 2015 was performed. Forty-one patients (mean age, 28.9 ± 7.6 years) with massive vaginal haemorrhage from GTN (including 27 cases of choriocarcinoma and 14 cases of invasive mole) were treated with SAE...

AIM: To evaluate retrospectively the impact of injection flow rate on arterial phase image degradation in liver magnetic resonance imaging (MRI) with gadoxetic acid (Gd-EOB-DTPA) compared to gadobutrol. MATERIALS AND METHODS: Two hundred consecutive patients who had undergone liver MRI were enrolled in this Health Insurance Portability and Accountability Act (HIPAA)-compliant institutional review board (IRB)-approved study and were divided into three groups. Group 1 (50 patients) and 2 (50 patients) had undergone MRI performed with gadoxetic acid (fixed 10 ml) at flow rate of 1 and 2 ml/s, respectively...

REVIEW
Y L Dai, A D King
Head and neck cancer affects more than 11,000 new patients per year in the UK(1) and imaging has an important role in the diagnosis, treatment planning, and assessment, and post-treatment surveillance of these patients. The anatomical detail produced by magnetic resonance imaging (MRI) is ideally suited to staging and follow-up of primary tumours and cervical nodal metastases in the head and neck; however, anatomical images have limitations in cancer imaging and so increasingly functional-based MRI techniques, which provide molecular, metabolic, and physiological information, are being incorporated into MRI protocols...
