This narrative literature review aims to identify the various factors that have significant impact on radiologists' visual search patterns. Identifying the factors that influences readers' visual search behaviour helps to understand their perception and interpretation of medical images, which in turn could lead to the development and implementation of effective strategies that could aid in improving the ability to detect abnormalities. Databases including PubMed, MedLine, Web of Science and ScienceDirect were searched using terms 'visual search', 'eye-tracking', 'radiology OR radiography', 'mammogram OR mammography' published since the early 1960s until June 30, 2016...

INTRODUCTION: Evidence that Deep Inspiration Breath Hold (DIBH) can reduce cardiac dose during left-sided breast radiation therapy (RT) has led to widespread uptake of this technology. There is a paucity of published information documenting the impact of this technique on the patient's treatment experience. The aim of this study was to develop a tool to assess the patient's experience with the introduction of DIBH using the Elekta® Active Breathing Coordinator (ABC) in a single institution...

INTRODUCTION: The management of prostate cancer has undergone significant advances since the introduction of 68 Ga-prostate-specific membrane antigen (68 Ga-PSMA) positron emission tomography (PET) scans. Data on the use of 68 Ga-PSMA PET scans in the setting of biochemical recurrence is widely available. Data on the use of 68 Ga-PSMA PET as an initial staging modality, however, is limited. The aim of this retrospective study was to compare the staging of patients with newly diagnosed prostate cancer between 68 Ga-PSMA PET and current conventional imaging modalities...

INTRODUCTION: Hyperbaric oxygen therapy (HBOT) is widely used for the treatment of the late effects of radiation therapy. We report a prospective observational cohort study of 51 patients designed to examine the effectiveness of hyperbaric oxygen treatment (HBOT) for xerostomia following radiotherapy. METHODS: Objective (saliva volume) and subjective (quality of life scoring and visual analogue scale (VAS) of discomfort) measurements associated with xerostomia were compared prior to commencement of HBOT, after 30 sessions (over 6 weeks) of HBOT at 243 kPa for 90 minutes daily for five days per week and at 6-week review (12 weeks from commencement)...

INTRODUCTION: Intraoperative radiation therapy (IORT) is an alternative to whole breast radiation following breast conserving surgery. Conventional breast IORT is limited by lack of cross-sectional imaging. In response, our institution developed Precision Breast IORT (PB-IORT) which utilizes intraoperative computed tomography (CT) images for confirmation of brachytherapy applicator placement and for treatment planning. The purpose of this study was to determine the utility of CT imaging in PB-IORT in the first 103 patients treated in two prospective clinical trials...

INTRODUCTION: Interfraction bladder motion is substantial and therefore many different adaptive radiotherapy approaches have been developed to accommodate that motion. Previous studies comparing the efficacy of those adaptive strategies have demonstrated that reoptimization (ReOpt) was dosimetrically superior when compared to Plan of the Day (POD) and Patient-specific PTV (PS-PTV). However, the feasibility of clinical implementation is dependent upon assessment of the resource burden...

Lung adenocarcinoma has a spectrum of appearances on CT, many of which mimic non-malignant processes. The general radiologist has a major role in guiding the management of abnormalities detected on chest CT and an awareness of these appearances is vital. We describe the protean imaging manifestations of lung adenocarcinoma.

INTRODUCTION: The need to measure reporting workload in teaching departments remains a current pertinent need. In Australia, the Pitman-Jones reporting RVUs have been in the public domain since 2003 (revised in 2009). These are expressed in arbitrary units. In New Zealand, single-site Christchurch Hospital reporting times have been validated and placed in the public domain. Concurrently, the RANZCR has been developing a formulaic descriptor lexicon for imaging studies (the Body System Framework)...

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...
