Radiation dose and risk to the lens of the eye during CT examinations of the brain
SummaryCataracts are the leading cause of blindness and visual disability worldwide. Of the known contributing factors to this condition, ionising radiation is considered the primary concern in a radiological context given the particular radiosensitivity of the lens of the eye. In light of the substantially increased application of computed tomography in brain imaging, an investigation of the relevent literature is warranted to assess thresholds, lens radiation doses and dose reduction techniques in respect to the cataractogenic risk of such examinations. The value and very existence of a lens dose threshold is debatable g...

Radionuclide lung scans for suspected acute pulmonary embolism: Single photon emission computed tomography (SPECT) or hybrid SPECT/CT?
AbstractIntroductionHybrid single photon emission computed tomography (SPECT) with CT (SPECT/CT) may improve diagnostic accuracy in suspected acute pulmonary embolism, but further research is needed. We evaluated whether the use of attenuation correction and/or the depiction of lung pathology with hybrid SPECT/CT could significantly reduce potentially false ‐positive ventilation–perfusion (VQ) SPECT studies or obviate the need for a ventilation study.MethodsTwo specialists (S1 and S2) reviewed prospectively acquired VQ SPECT/CT in 165 patients.

Recent clinical applications of external beam radiotherapy for hepatocellular carcinoma according to guidelines, major trials and meta ‐analyses
SummaryExternal beam radiotherapy (EBRT) for hepatocellular carcinoma (HCC) has not been widely used due to lack of high ‐level evidence, despite its potent local therapeutic effect. While clinical evidence has accumulated and meta‐analyses of observational studies have provided integrated information to help in clinical decision‐making, a recent randomized trial demonstrated the benefit of EBRT in cases of HCC with major vessel invasion. Based on these trends, the efficacy of EBRT has been better recognized, and EBRT has been more frequently recommended in several international treatment guidelines newly updated in ...

Contemporary practice patterns of stereotactic radiosurgery for brain metastasis: A review of published Australian literature
SummaryThere has been a shift in the management of brain metastasis (BM), with increasing use of stereotactic radiosurgery (SRS) and delaying/avoiding whole ‐brain radiotherapy (WBRT), given the concern regarding the long‐term neurocognitive effect and quality of life impact of WBRT. It is, however, unclear as to the contemporary practice pattern and outcomes of SRS in Australia.

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)

Her intracranial IgG4 disease had a near‐complete response to radiosurgery and is still controlled six years later, so this case represents what we believe to be the first reported use of radiotherapy in the treatment of intracranial IgG4‐related disease.

Simultaneous positron emission tomography and magnetic resonance imaging for the detection and characterisation of liver lesions in patients with colorectal cancer: A pictorial review
SummaryPatients with colorectal cancer undergo frequent diagnostic imaging to stage the extent of metastatic disease and assess response to treatment. Imaging is typically via diagnostic contrast ‐enhanced CT or combined FDG‐PET/CT. However, recent research has demonstrated promising benefits of combined FDG‐PET/MRI in oncologic imaging due to the superior soft‐tissue contrast of MRI. The extent of both intrahepatic and extrahepatic disease is important in establishing treatment opti ons for colorectal cancer patients, and FDG‐PET/CT and dedicated liver imaging are often both required. FDG‐PET/MRI offers the ad...

Diagnostic performance of 18F ‐fluorodeoxyglucose positron emission tomography in the evaluation of glioma
ConclusionThe combination of FDG ‐PET/CT and gadolinium‐enhanced MRI demonstrated marked improvement in identifying potential high‐grade disease over each modality alone. Increased FDG uptake without gadolinium enhancement rarely occurred and identified high‐grade histology in a small number of patients. Due to limited sens itivity and NPV, a negative FDG‐PET/CT alone, or in combination with MRI, should not guide a decision for observation where surgery would otherwise be recommended.
