The Royal Australian and New Zealand College of Radiologists (RANZCR) Radiology Written Report Guideline was first issued in 2011. A survey-based consultation of clinical radiology members of the college in 2015 found that the vast majority of 235 respondents supported all components of the guideline. Since the original guideline was developed, considerable new research has been published about radiology reporting, particularly regarding structured/template reports. In 2016/17 a RANZCR working group used the consultation results, stakeholder feedback and recent research to develop revised guidelines...

INTRODUCTION: As interventional radiology (IR) adopts an increasingly pivotal role within therapeutic medicine, it is essential that medical students gain exposure to IR so as future doctors, they can fulfil the growing demand for interventional radiologists (IRs) and make appropriate referrals to IRs. Nonetheless, several international studies have reported no or little representation of IR in medical schools. Our study aims to assess the current awareness, exposure, knowledge and attitudes about IR among Australian medical students, so as to provide preliminary data on whether IR teaching in Australian medical schools needs improvement...

INTRODUCTION: We evaluated the impact of MRI-based target delineation on toxicity and tumour control after implementation of a protocol to incorporate MRI while minimizing impact on overall procedural time. METHODS: We retrospectively reviewed outcomes for a cohort of 96 consecutive patients who received intracavitary brachytherapy for cervical cancer at our institution during 2012-2016. Starting in October 2014, an outpatient MRI was obtained for patients after Smit sleeve placement and first insertion to assess concurrent chemoradiotherapy tumour response...

Colorectal cancer is the third most common malignancy worldwide, and rectal cancer (RC) accounts for 29% of all cases. Local staging of RC is crucial for the purposes of addressing patients appropriately to surgery alone or to preoperative chemoradiotherapy (pCRT) followed by total mesorectal excision (TME). Combined pCRT and TME may negatively affect rectal function, so rectum-sparing approaches such as transanal local excision have been proposed as an alternative to TME for patients showing a major or complete clinical response on restaging after pCRT...

Advanced techniques have been described to remove embedded inferior vena cava (IVC) filters including the loop snare and modified loop snare (Hangman) techniques. Retrieval of embedded filters have been associated with higher rates of complications including IVC injury and stenosis. We report two challenging embedded retrievals complicated by IVC injury and haemorrhage. Haemostasis was successfully achieved with prolonged balloon tamponade, suggesting that injury to the IVC during filter retrieval may not need urgent surgery...

Inferior vena cava filters should be ideally placed in the infrarenal caval segment to maintain renal vein outflow and thereby patency; however, in certain circumstances a suprarenal position may be required. Suprarenal filters are subject to the same risks as for infrarenal filters including tilt. While many advanced techniques have been used for infrarenal filter retrievals, there is a paucity of evidence supporting the use of these retrieval techniques in the suprarenal segment. We show a case of successful retrieval of a suprarenal filter using the Hangman technique...

We present a rare case of giant adrenal pseudocyst as a cause of right upper quadrant (RUQ) pain and highlight the typical multimodality imaging features. The case demonstrates the imaging features associated with giant adrenal pseudocysts to aid accurate and timely diagnosis. Despite the rarity of these lesions they are important to consider as benign lesions can closely mimic malignant ones. Unenhanced and contrast-enhanced CT is the imaging of choice for adrenal cysts. However, MRI can provide more exquisite assessment of cystic, solid and enhancing components...

INTRODUCTION: Pelvic MRI has an increasingly important role in the evaluation of non-malignant uterine pathology including uterine leiomyomas, adenomyosis and endometriosis. Normal physiological myometrial junctional zone transient contractions can also be identified on MRI and have the potential to act as pathology mimics. This study aims to evaluate both the incidence of visible physiological contractions in premenopausal female pelvic MRI and also to support the routine acquisition of a repeat T2 sagittal sequence to differentiate transient physiological contractions from true underlying pathology and therefore improve observer confidence...

INTRODUCTION: For early-stage hepatocellular carcinoma (HCC) patients, ablative strategies are potentially curative treatment options. Stereotactic body radiotherapy (SBRT) has emerged as a promising ablative therapy, although its comparison with radiofrequency ablation (RFA) remains confined to a single institution retrospective review. We sought to characterize the comparative outcomes and cost between the two treatment strategies. METHODS: We conducted a secondary analysis of the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database (2004-2011) and identified adult patients with stage I or II HCC and treated with RFA or SBRT as the initial treatment within 6 months of diagnosis...

INTRODUCTION: Highly specific preoperative localizing test is required to select patients for minimally invasive parathyroidectomy (MIP) in lieu of traditional four-gland exploration. We hypothesized that Tc-99m sestamibi scan interpretation incorporating numerical measurements on the degree of asymmetrical activity from bilateral thyroid beds can be useful in localizing single adenoma for MIP. METHODS: We devised a quantitative interpretation method for Tc-99m sestamibi scan based on the numerically graded asymmetrical activity on early phase...

Diseases due to spinal and musculoskeletal degeneration are a common cause of disability worldwide. In the past few years, there has been widespread increase in the use of imaging in these conditions. However, the years lived with a disability has not declined. There is a growing body of evidence that imaging in spinal and musculoskeletal conditions due to degeneration and ageing is unnecessary and contributes to increasing costs. More worrying is the evidence that imaging may also cause harm due to prevalent use of cortisone injections and surgical procedures that are justified on the basis of a radiology report...

INTRODUCTION: The clinical target volume (CTV) delineation is crucial for tumour control and normal tissue protection. This study investigated the contralateral extension of nasopharyngeal carcinoma (NPC) in patients with a clinically diagnosed unilateral tumour to pursue the possibility of CTV reduction. METHODS: Twenty NPC patients with localized tumours confined to only one side of the nasopharynx as shown by magnetic resonance imaging and fibreoptic endoscopy were selected for biopsy...

Pancreatic transplantation is a therapeutic option for both poorly controlled cases of diabetes mellitus and patients with advanced diabetic nephropathy. It is important for radiologists to know the different surgical techniques as well as the typical radiological appearance after pancreatic transplantation, in order to accurately identify the complications. These complications can be classified according to the period of time after the transplantation in which they typically occur: immediate (first 24 hours), early (24-72 hours), intermediate (72 hours to weeks) and late (months)...

The purpose of this study is to evaluate the effectiveness and safety of stereotactic body radiation therapy (SBRT) in the management of oligometastatic recurrent prostate cancer (PCa) by means of a systematic review. Six databases were searched (CENTRAL, Embase, LILACS, PubMed, Scopus and Web of Science). Additionally, hand-searching and grey literature search were performed. The main outcomes were progression-free survival (PFS) and toxicity rates. Androgen deprivation therapy-free survival (ADT-FS), local control, pattern of recurrence, cancer-specific survival and overall survival were also assessed...

INTRODUCTION: Skin bolus may routinely be used in the perineum to build up the surface dose in the treatment of anal cancer (ACC); this may contribute to significant acute skin toxicity. Skin bolus may not be needed with the introduction of modern radiotherapy techniques if these planning techniques would achieve adequate surface dose. Our study is to ascertain if appropriate skin dose can be achieved without the use of bolus when VMAT is used in the treatment of ACC. METHODS: The study includes 10 ACC patients treated with VMAT radiotherapy...

INTRODUCTION: To evaluate whether age is a predictor of pain response after radiotherapy for painful bone metastasis (BM). METHODS: Between June 2010 and June 2014, 204 patients with BM undergoing palliative radiotherapy participated in a multicentre prospective study. Patients completed the Brief Pain Inventory (BPI) to rate the intensity pain (from 0 to 10) at baseline and 4 weeks after radiotherapy. To determine which variables predicted pain response and particularly whether age is a predictor, logistic regression analysis was used...

INTRODUCTION: The development of dual-energy CT and metal artefact reduction software provides a further chance of reducing metal-related artefacts. However, there have been only a few studies regarding whether MARs practically affect visibility of structures around a metallic hip prosthesis on post-operative CT evaluation. METHODS: Twenty-seven patients with 42 metallic hip prostheses underwent DECT. The datasets were reconstructed with 70, 90 and 110 keV with and without MARs...

INTRODUCTION: This study was performed to assess the relationship between tumour response and radiation dose in equivalent 2 Gy per fraction (EQD2). METHOD: A retrospective cohort analysis of 21 patients with a diagnosis of intracranial haemangiopericytoma between 2000 and 2013 was included in this study. A total of 39 lesions were analysed. The equivalent dose in 2 Gy per fraction was calculated by assigning an alpha-beta ratio of 12 Gy. A paired t-test compared dose (EQD2) and tumour response, and as the outcome was binary, a logistic regression analysis was performed...

Radiation oncology trainees in Australia and New Zealand have relatively high levels of emotional exhaustion and depersonalisation which are core components of burnout. The stresses of a demanding clinical load, studying for exams as well as family commitments are all contributing factors. Self-Deter mination Theory (SDT) provides a framework for optimising motivation which may be intrinsic or extrinsic. The three core components of SDT are competence, relatedness and autonomy. These factors should be addressed at a college level, Institutional and a personal level if the best outcomes are to be achieved...
