INTRODUCTION: In Ghana, trans-abdominal ultrasonography is the main sonographic method of prostatic volume evaluation. The examinations are done when the patient's bladder is full. However, the delay and the discomforting experiences associated with a full bladder have been well documented. In an attempt to investigate other less discomforting options, this study was undertaken to determine if sonographic transabdominal prostatic evaluations performed at urinary bladder volumes of 50-99 mL differ significantly to evaluations done at volumes of 100-199, 200-299 and 300-399 mL...

The Australian radiotherapy profession is challenged by job dissatisfaction, stress, burnout and unfavourable attrition. This paper will use psychological models to discuss the confluence of job demands, resources and personal characteristics that contribute to these challenges. Factors contributing to burnout and attrition amongst Australian Radiation Therapists will be explored, and a number of leadership strategies will be introduced to improve workplace culture. These strategies - aligned with positive psychology - seek to address staff engagement, emotional needs, and job stressors...

Trauma to the facial area accounts for a significant number of admissions to the emergency department. Diagnostic imaging is almost always required, and is critical in determining patient management. Multi-detector computed tomography (MDCT) appears consistently in the literature as the gold-standard imaging modality for facial bones, but results in a high radiation dose to the patient. This makes the application and advancement of dose reduction and dose optimisation methods vital. This narrative review presents a critical analysis of the literature concerning diagnostic imaging of facial bone trauma, with an emphasis on dose reduction methods for MDCT...

INTRODUCTION: Diagnostic coronary angiography (CA) uses ionising radiation with relatively high doses, which impact on both patients and staff. This study sought to identify which patient and procedural factors impact patient and operator dose the most during CA. METHODS: Patient and procedure related variables impacting on Kerma area product (PKA ) and operator dose (OD) were collected for 16 months. Procedures were separated into 10 different procedure categories...

Radiation dose to patients undergoing cardiac imaging procedures in cardiac catheterisation laboratories (cath labs) can be relatively high, so implementing strategies to reduce dose is important. Lowering the fluoroscopy pulse rate is a simple, yet effective method to reduce radiation dose. Sensible, iterative changes made in this area have the potential for significant patient and staff radiation dose reduction.

INTRODUCTION: The majority of pancreatic cancers present locally advanced and carry a high mortality rate. Treatment is challenging, with mixed data suggesting use of chemotherapy alone or in combination with radiotherapy. The use of radiotherapy has previously been limited due to lack of ability to deliver radiation to the tumour mass without causing significant toxicity to surrounding organs. Stereotactic body radiotherapy (SBRT) allows delivery of higher biologically equivalent dose in a shorter treatment duration...

INTRODUCTION: For gynaecological cancers, volumetric modulated arc therapy (VMAT) offers comparable plan quality with shorter treatment delivery times when compared to intensity modulated radiation therapy (IMRT). METHODS: The clinical IMRT plans of twenty gynaecological cancer patients were compared with a retrospectively generated VMAT plan. Planning target volume (PTV) metrics compared were D95 > 99%, homogeneity index, and conformity index. Organs at risk (OAR) doses compared were bladder V45 < 35%, bowel V40 < 30%, femoral head and neck (FHN) V30 < 50%, V44 < 35% and V44 < 5%...

INTRODUCTION: While use of a thermoplastic mask during radiotherapy (RT) treatment for head and neck cancer (HNC) is an essential component of safe patient care, there is little understanding of the extent to which this evokes anxiety (i.e. "mask anxiety") for the person undergoing treatment. METHODS: A mixed method, convergent design was used to examine the prevalence and experience of mask anxiety using two clinical cohorts. In phase one, a cohort of 100 patients undergoing RT for HNC were assessed for self-perceived mask anxiety using a modified distress thermometer screening tool...

INTRODUCTION: The objectives of this study were to identify knowledge gaps and/or perceived limitations in the performance of paediatric appendiceal ultrasound by Australasian sonographers. We hypothesised that: sonographers' confidence in visualising the appendix in children was poor, particularly outside predominantly paediatric practice; workplace support for prolonging examinations to improve visualisation was limited; and the sonographic criteria applied in diagnosis did not reflect contemporary literature...

INTRODUCTION: Radiographers are at times required to provide preliminary information on plain radiography when significant findings are identified. The aim of the study was to evaluate the effectiveness of two short training modules to improve the accuracy of image interpretation of the appendicular skeleton amongst a group of radiographers. METHODS: Eight radiographers volunteered to participate in the study. All undertook a pre-test and, following delivery of course materials, an immediate post-test for two consecutive modules...

INTRODUCTION: To implement the modulated arc total body irradiation (MATBI) technique within the existing infrastructure of a radiation oncology department. The technique needed to treat paediatric patients of all ages, some of whom would require general anaesthesia (GA). METHODS: The MATBI technique required minor modifications to be incorporated within existing departmental infrastructure. Ancillary equipment essential to the technique were identified and in some cases custom designed to meet health and safety criteria...

We describe the use of radiotherapy for parotid IgG4-related disease (IgG4-RD), initially misdiagnosed as Kimura's disease, with sustained good partial response in a 37-year-old male. To the best of our knowledge, this is the first reported case of radiation for extra-orbital IgG4-RD, albeit inadvertently.

Radiation recall is an uncommon phenomenon describing an acute localised inflammatory toxicity affecting tissue previously exposed to radiotherapy. It is precipitated by administration of certain medications, including chemotherapy. We describe a case involving a 50-year-old Aboriginal male smoker from a remote community in Northern Australia who underwent treatment for stage IV non-small cell lung cancer with localised radiotherapy to the primary right upper lung lobe tumour. This was followed by a course of gemcitabine, which was ceased prematurely after four cycles when he presented with radiation recall to his right pectoralis major...

Three-dimensional (3D) printing and medical imaging have a complementary association, the benefits and application areas of which are increasingly documented and further illustrated in this journal publication. Medical imaging data can be appropriately processed (i.e. segmented) to provide the geometric information from which accurate and realistic 3D medical models can be generated. The resulting models can be printed in a range of different materials to suit their use as phantoms in medical radiation and imaging studies, for medical imaging education and training or patient communication...

Diagnostic imaging pathways are developed to ensure that medical imaging examinations are appropriately selected and referred by clinicians with the aim of justifying the use of imaging modalities for clinical diagnosis. Failing to comply with the imaging pathways or guidelines results in exposing patients to unnecessary ionising radiation due to malpractice of imaging referrals. This editorial provides a comment on a recent study reporting very high percentage of general x-ray imaging referrals which did not or partially met the imaging pathways in an emergency department...

INTRODUCTION: The underpinning principles of radiation protection are justification, optimisation and limitation. Each medical imaging referral that uses ionising radiation must balance the justification of exposure to radiation against the benefits of the examination. Scrutiny of justification is the role of radiographers, for general radiography, and is usually performed using the clinical details provided on the referral. International studies report up to 77% of medical imaging examinations are unjustified or inappropriate...
