Predictive value of computed tomography in identifying extracapsular spread of cervical lymph node metastases in p16 positive oropharyngeal squamous cell carcinoma.

J Med Imaging Radiat Oncol 2019 Apr 11. Epub 2019 Apr 11.

Department of Otolaryngology, Head and Neck Surgery, Royal Adelaide Hospital, University of Adelaide, Adelaide, South Australia, Australia.

Background: Extracapsular spread (ECS) of lymph node metastases is associated with poor prognosis and is an indication for adjuvant chemoradiotherapy. Accurately identifying ECS using imaging may allow us to recommend primary chemoradiotherapy to avoid trimodality treatment. We investigated the accuracy of staging CT in diagnosing ECS in P16 + oropharyngeal squamous cell carcinoma (OPSCC). Read More

J Med Imaging Radiat Oncol 2019 Mar 12. Epub 2019 Mar 12.

Department of Radiology, Alfred Health, Melbourne, Victoria, Australia.

Introduction: Computed tomography-guided cervical nerve root corticosteroid injections are a commonly performed procedure for cervical radiculopathy. There have been major complications such as spinal cord infarction and posterior circulation stroke reported mostly with X-ray fluoroscopic-guided methods, however, there is relatively little data on the safety of newer CT-guided methods. The purpose of this study was to identify any major complications and evaluate the rate of minor complications from CT-guided cervical nerve root corticosteroid injections performed in a tertiary public hospital.

Unexpected significant findings non-related to prostate cancer identified using combined prostate-specific membrane antigen positron emission tomography/CT and diagnostic CT scan in primary staging for prostate cancer.

J Med Imaging Radiat Oncol 2019 Mar 6. Epub 2019 Mar 6.

Wesley Medical Imaging, The Wesley Hospital, Brisbane, Queensland, Australia.

Introduction: There is increasing scientific evidence that whole-body Gallium-68 prostate-specific membrane antigen ( Ga-PSMA) positron emission tomography/computed tomography (PET/CT) improves the sensitivity of prostate cancer detection above standard staging radiology. Diagnostic IV-contrasted CT scanning offers high-quality recognition and delineation of organs and structures with a high sensitivity and specificity for diagnoses of many non-prostate pathologies. At our institution, imaging for prostate cancer staging and restaging involves a Ga-PSMA PET/CT scan combined with a diagnostic IV-contrasted CT scan of the head, neck, chest, abdomen and pelvis.

Visceral adipose ratio as a novel predictor for acute bowel toxicity in patients receiving pelvic radiation: Preliminary dosimetric analysis and clinical validation.

J Med Imaging Radiat Oncol 2019 Mar 4. Epub 2019 Mar 4.

Department of Radiation Oncology, University of Kansas Cancer Center, Kansas University Medical Center, Kansas City, Kansas, USA.

Introduction: During 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 applied this as a correction factor to standard bowel bag dosimetric measures, hypothesizing that corrected SB measures would better correlate with acute toxicity.

Pictorial review of Morel-Lavallée lesions.

J Med Imaging Radiat Oncol 2019 Apr 16;63(2):212-215. Epub 2019 Jan 16.

Women and Children Hospital Adelaide, Benson Radiology, Adelaide, South Australia, Australia.

A Morel-Lavallée lesion is a post-traumatic soft tissue degloving injury which presents as a haemolymphatic mass or collection. Morel-Lavallée lesions are the result of direct trauma or shearing forces abruptly separating skin and subcutaneous tissue from underlying fascia causing disruption of perforating vessels and nerves, creating a potential space that may fill with blood, lymph and debris forming a collection. Morel-Lavallée lesions usually occur adjacent to osseous protuberances, most commonly along the greater trochanter. Read More
