Aims and background: we evaluate CT-3Tesla MRI fusion in conformal radiotherapy for localized prostate cancer.Methods: 18 consecutive patients underwent a 3T MRI scan under radiotherapy planning conditions, after the CT scan. Bowel and bladder preparation were prescribed. CT and MR images were automatically fused; prostate and seminal vesicles were contoured on CT and on MRI, organs at risk wer...

T introduction of nerve‐sparing technique is one of the most significant advances in the surgical treatment of prostate cancer and heralded a shift from a curing cancer at all‐cost model to a curing cancer and preserving quality of life model.1,2 In a recent article published in Lancet Oncology in May, Lee et al.3 reviewed the concept of vessel‐sparing and functional anatomy‐based radiotherapy ...

Radiotherapy is one of the treatment options for locally advanced prostate cancer; however, with standard radiation doses, it is not always very effective. One of the strategies to improve the efficiency of radiotherapy is increasing the dose. In this study, to increase tumor local control rates, a new radiotherapy method, known as dose painting (DP), was investigated. To compare 3-dimensional ...

Background: The rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. Materials and Methods: The system is composed of a micro positron emission tomography (mPET), 7T magnetic resonance imaging (MRI), and a customized MRI-compatible foc...

BACKGROUND Squamocellular anal carcinoma is increasingly diagnosed in patients with risk factors. METHODS State-of-the-art imaging with magnetic resonance imaging (MRI) using phased-array coils and volumetric multidetector computed tomography (CT) provides detailed visualisation of anal disorders, identification and extent assessment of neoplastic tissue, detection and characterisation of nod...

We report surgical treatment and radiotherapy of an extremely rare case of malignant epidermoid cyst located in cerebellopontine angle. MRI and CT demonstrated the lesion with partial enhancement and calcification. During operation, we found the tumor attached tightly to surrounding tissue. Finally we achieved near total resection of it. Histopathology confirmed the diagnosis of epidermoid cyst...

BACKGROUND The purpose of this study was to demonstrate how magnetic resonance imaging (MRI) patient position protocols influence registration quality in patients with oropharyngeal cancer undergoing radical radiotherapy and the consequences for gross tumour volume (GTV) definition and radiotherapy planning. METHODS AND MATERIALS Twenty-two oropharyngeal patients underwent a computed tomograp...

Novel technology has made dynamic magnetic resonance imaging (MRI) of lung motion and lung tumour mobility during continuous respiration feasible. This might be beneficial for planning of radiotherapy of lung tumours, especially when using high precision techniques. This paper describes the recent developments to analyze and visualize pulmonary nodules during continuous respiration using MRI. B...

Morphology as demonstrated by CT is the basis for radiotherapy planning. Intensity-modulated and adaptive radiotherapy techniques would greatly benefit from additional functional information allowing for definition of the biological target volume. MRI techniques include several which can characterize and quantify different tissue properties and their tumour-related changes. Results of perfusion...
