Phantom and Animal Study of a Robot-Assisted, CT-Guided Targeting System using Image-Only Navigation for Stereotactic Needle Insertion without Positional Sensors.

Purpose: To evaluate the feasibility and accuracy of a robotic system to integrate and map computed tomography (CT) and robotic coordinates, followed by automatic trajectory execution by a robotic arm. The system was hypothesized to achieve a targeting error of <5 mm without significant influence from variations in angulation or depth.

Materials And Methods: An experimental study was conducted using a robotic system (Automated Needle Targeting device for CT [ANT-C]) for needle insertions into a phantom model on both moving patient table and moving gantry CT scanners.

SingHealth Radiology Archives pictorial essay Part 1: cardiovascular, respiratory and neurological cases.

The Singapore Health Services cluster (SingHealth) radiology film archives are a valuable repository of local radiological cases dating back to the 1950s. Some of the cases in the archives are of historical medical interest, i.e.

Letter to the editor: Comment on a case report of thermal injury to spinal cord, a rare complication of percutaneous microwave spine tumour ablation.

Microwave ablation of the spine is an effective treatment option for patients with symptomatic osseous metastases. It is an increasingly common procedure in clinical practice and can be performed in conjunction with other procedures such as vertebroplasty and nerve root blocks. Multiple studies have demonstrated the safety and efficacy of the percutaneous ablation; however potential complications can arise.

Review of Junior Resident Plain Film Reporting and Audit in Singapore.

Background: Graduate medical education in Singapore recently underwent significant restructuring, leading to the accreditation of residency programs by the Accreditation Council for Graduate Medical Education-International (ACGME-I). In radiology, this involved a change in teaching and quality assurance of plain film (PF) reporting. PF reported by junior residents (postgraduate year 1-3) are subject to a 50% random audit.
