Image Guided Ablations for Thyroid Tumours

Image-guided percutaneous ablation of pulmonary tumours

Image-guided percutaneous local therapy using radiofrequency ablation (RFA) and laser-induced interstitial thermotherapy (LITT) has been used in liver tumours and non-hepatic lesions (e.g. osteoid osteoma) for several years [1–4]. It has been shown to be effective and safe and can usually be performed under local anaesthesia. Recently, percutaneous tumour ablation has also been introduced for l...

Image guided focused ultrasound delivery of macromolecular drugs in tumours

Background/introduction Drug delivery using focused ultrasound (focal drug delivery) has attracted significant interest during the last few years. Focused Ultrasound (FUS) can induce local tissue hyperthermia, increasing blood flow and vascular permeability, which then enhances the uptake of therapeutics by target tissues. Although a number of studies have focused on nanoparticles (e.g. thermos...

Image-guided endoscopic transsphenoidal removal of pituitary tumours.

BACKGROUND With continuing advancements in minimally invasive endoscopic nasal and sinus surgical techniques, image-guided endoscopic transsphenoidal approaches to the pituitary gland and anterior skull base have progressively become more popular. METHODS Clinical records were reviewed retrospectively from 2001 to 2006. Twenty-nine consecutive patients with pituitary tumours underwent transna...

A fast model for prediction of respiratory lung motion for image-guided radiotherapy: A feasibility study

Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...
