PURPOSE This study used prospective swallowing data to establish the following: (1) whether doses to the pharyngeal constrictor muscles (PCMs) were significantly associated with swallowing outcomes; and (2) a mean dose constraint to aim for in intensity modulated radiation therapy planning. METHODS AND MATERIALS The PCMs were contoured and radiation dose(More)
Magnetic resonance imaging is an excellent technique for imaging the tendons and the ligaments of the ankle. Owing to the advantage of detailed demonstration of soft-tissue structures and capability for multiplanar demonstration of the ankle ligaments and tendons, MRI has been increasingly used in the evaluation of the ligamentous and the tendon injuries of(More)
BACKGROUND Demand for screening breast magnetic resonance imaging (MRI) for women with a hereditary predisposition to breast cancer has increased since the introduction of a medicare item number. To aid future service planning, we examined the practicalities of establishing and running a breast MRI screening programme for high risk women and to describe the(More)
High-risk skin cancer arising on the upper limb or trunk can cause axillary nodal metastases. Previous studies have shown that axillary radiotherapy improves regional control. There is little published work on technique. Technique standardization is important in quality assurance and comparison of results especially for trials. Our technique, planned with(More)
To describe the technical radiological aspects of isolated limb infusion (ILI) to assist those procedural radiologists who carry out ILI on an occasional only basis and to inform the Australian radiologist community about this deserving but relatively little known radiological procedure. Retrospective audit of radiological catheter placement for 23 lower(More)
In April 2004, Melbourne's Peter MacCallum Cancer Centre, Australia's only stand-alone dedicated cancer hospital, became the first Australian site to offer digital mammography (DM). In the first year of DM operation, 1208 mammograms were performed on 1157 women; 17 new cases of invasive carcinoma and six new cases of ductal carcinoma-in-situ (DCIS) were(More)
