Lung Lesions Biopsy in Children by Computed Tomography (CT) Fluoroscopy Guided Versus Conventional CT Scan Guided

Abstract Background Computed tomography (CT)-guided biopsy of the lung is a well-established method of diagnosis. The aim of this study was to determine the success rate of fluoroscopic CT (FCT) and conventional CT (CCT) in needle navigation biopsies from the lung lesions. Materials and Methods A total of 78 patients were prospectively enrolled to receive CT-guided biopsy with (group I, n=2...

Atrial fibrillation ablation guided by computed tomography.

video). Subsequently, the 4 PVs were electrically disconnected by circumferential radiofrequency application at the ostia (pink circles). There were no complications, the patient has had no recurrent AF, and her functional class improved (class I) during follow-up. More precise anatomic information about the LA and PVs obtained with new imaging techniques has contributed greatly to the advances...

[Computed tomography guided fine needle aspiration biopsies].

Computed tomography (CT) allows the performance of fine needle aspiration biopsies in situations in which ultrasound or conventional X rays do not correctly visualize the lesion or the needle tract. One hundred four patients with a clinical suspicion of neoplasia were subjected to CT guided percutaneous aspiration biopsies in a lapse of 6 years. The most frequently biopsied organs were the lung...

Percutaneous computed tomography-guided oesophageal needle biopsy.

Sir, Biopsies of suspicious lesions in the oesophagus can be readily performed via a flexible endoscope in most settings. However, structuring lesions may require a rigid endoscope under general anaesthesia or a percutaneous approach to successfully biopsy. The percutaneous approach however, is rarely used with upper gastrointestinal tract lesions. We describe the fine needle aspiration (FNA) o...
