A simple algorithm to predict non ‐compliance with organ at risk dose‐volume constraints when planning intensity modulated post‐prostatectomy radiation treatment: ‘Why we should put the CART before the horse’
ConclusionsA simple algorithm was developed to predict plan quality by using the OV of the bladder and rectum with the PTV. This algorithm may be used a priori to assess the planning process in the context of variable anatomy, and to optimise planning quality and efficiency.

Radiology teaching for interns: Experiences, current practice and suggestions for improvement
ConclusionThis study has demonstrated a paucity of radiology teaching provided to interns in a large Australian teaching hospital. As they request and interpret high volumes of diagnostic imaging, skills in this domain are paramount in the provision of safe, effective and timely patient care. The results are being used in the design and implementation of a high ‐quality radiology teaching programme to improve junior doctors’ skill and develop the radiologist–clinical referrer interface.

Retrospective review of CT brain image quality, diagnostic adequacy and radiation dose in a paediatric population imaged at a non ‐paediatric tertiary hospital
AbstractIntroductionMinimising radiation exposure in paediatric imaging examinations whilst maintaining acceptable diagnostic quality continues to present a challenge. The aims of this study were to assess institutional compliance of paediatric CT brain (CTB) examinations performed in an adult hospital with ARPANSA radiation dose recommendations and to compare qualitative CTB diagnostic acceptability with objective imaging parameters and radiation dose.MethodsA retrospective review of 115 consecutive paediatric CTB examinations was undertaken at an adult tertiary referral centre in Australia over a 2 ‐year period.

Image quality comparison between model ‐based iterative reconstruction and adaptive statistical iterative reconstruction chest computed tomography in cystic fibrosis patients
AbstractIntroductionCystic fibrosis (CF) predominantly affects young adults. Accurate radiological assessment of pulmonary disease is vital for predicting exacerbations, one of the leading causes of morbidity and mortality. We evaluated the image quality of model ‐based iterative reconstruction (MBIR) ultra‐low‐dose CT chest (ULD‐CT) in CF evaluation.MethodsWe compared ULD ‐CT with standard adaptive statistical iterative reconstruction (ASIR) low‐dose CT (LD‐CT). Subjective assessment of contrast and noise were performed for each study. Background noise, signal to noise ratio (SNR) and contrast to noise ratio...

Temporal impact of the publication of guidelines and randomised evidence on the adoption of hypofractionated whole breast radiotherapy for early ‐stage breast cancer
ConclusionThe temporal uptake pattern and the predictors of adjuvant HF ‐WBRT use in early breast cancer patients largely reflected the accumulating clinical evidence and the publication of the consensus guidelines. This study identified potentially modifiable factors associated with slower‐than‐expected uptake rate of HF‐WBRT. Understanding why there is variabi lity in clinicians’ readiness to adopt the abbreviated treatment despite the availability of advanced radiotherapy techniques and the updated evidence is an important step towards formulating effective strategies to optimise the radiotherapeutic manag...

Retrospective analysis of breast radiotherapy treatment plans: Curating the ‘non‐curated’
ConclusionThis paper exemplifies the data cleansing and data analysis steps that may be completed using existing treatment planning data, to provide individual radiation oncology departments with access to information on their own patient populations. Clearly, the well ‐planned and systematic recording of new, high quality data is the preferred solution, but the retrospective curation of non‐curated data may be a useful interim solution, for radiation oncology departments where the systems for recording of new data have yet to be designed and agreed.

Lu177 ‐PSMA therapy for men with advanced prostate cancer: Initial 18 months experience at a single Australian tertiary institution
ConclusionInitial experience at our site supports the use of LuPSMA as an emerging safe and effective treatment for mCRPC. Since introducing LuPSMA therapy at our institution, 44.9% of patients have experienced a decline in PSA level  ≥ 50% with low or minimal toxicity. This is an important finding as these patients had previously exhausted all available treatment options. Overall, we have found patients and their primary care doctors have eagerly accepted LuPSMA as another line of defence against mCRPC. (Source: Journal of Medical Imaging and Radiation Oncology)

Common and uncommon imaging features of abdominal tuberculosis
SummaryDespite the advances in the medical care, tuberculosis (TB) still remains an important health problem. This is particularly relevant to the developing countries as well as the immunocompromised population in the developed world. Multidrug resistance poses another challenge and may be responsible for increasing incidence of TB, to some extent. The respiratory system is the most commonly involved, although any organ system may be affected. Abdominal involvement occurs in 11 –12% of the patients with extrapulmonary TB. The clinical features of abdominal TB are nonspecific. Imaging plays an important role in the d...

Visceral adipose ratio as a novel predictor for acute bowel toxicity in patients receiving pelvic radiation: Preliminary dosimetric analysis and clinical validation
AbstractIntroductionDuring radiation treatment planning, the small bowel (SB) is often contoured as a ‘bowel bag’ encompassing the entire peritoneal space that may be occupied by SB. This method incorporates large volumes of visceral adipose, potentially resulting in misleading estimates of radiation dose to the SB. We evaluated the relative volume of adipose within the peritoneal space and appl ied this as a correction factor to standard bowel bag dosimetric measures, hypothesizing that corrected SB measures would better correlate with acute toxicity.MethodsEighteen consecutive patients receiving pelvic radiat...

Dynamic assessment of sternoclavicular joint instability using four ‐dimensional computed tomography
SummaryChronic post ‐traumatic sternoclavicular joint (SCJ) instability can be debilitating and result in restriction of normal daily activities.

Wide‐volume dynamic four‐dimensional computed tomography (4D CT) can con fidently diagnose chronic post‐traumatic SCJ instability. This can aid surgeons in pre‐operative planning and help to triage patients into surgical or non‐surgical candidates.
