We describe a method of performing lower cervical nerve root block (CNRB) with CT fluoroscopy in patients with large body habitus using the swimmer's position. This approach reduces image noise with acceptable visualization of vital structures and improved foraminal/root access. Anticipated use of the swimmer's position coupled with minimally modified radiation exposure parameters can limit rad...

We have developed a teaching programme for non-radiologists who use fluoroscopy, which includes techniques for reducing the radiation received by the patient and the surgeon during orthopaedic procedures. The techniques resolve around the radiation protection concepts of time, distance and shielding. The programme has been very successful in reducing the total fluoroscopy times of orthopaedic s...

OBJECTIVE The Image Gently Campaign of The Alliance for Radiation Safety in Pediatric Imaging seeks to increase awareness of opportunities to lower radiation dose in the imaging of children. Pause and Pulse is the most recent phase of the campaign, addressing methods of dose optimization in pediatric fluoroscopy. CONCLUSION This article discusses 10 steps that can be taken for fluoroscopic do...

Valvular heart disease is a growing field, and the number of new approaches for percutaneous treatment is increasing rapidly. These procedures usually cannot be performed with fluoroscopy alone; allowing echocardiography to be an essential role inside the Cath Lab. Three-dimensional echocardiography, and the introduction of a novel imaging modality that integrates live echocardiography and live...

This report details a method of percutaneous, transluminal retrieval of an intracardiac foreign body using fluoroscopy in combination with intracardiac echocardiography. During retrieval, intracardiac echocardiography (ICE) provided real-time anatomic localization of a constantly moving, almost radiolucent micropuncture coaxial dilator fragment with respect to the tricuspid and pulmonary valves...

fluoroscopy time, which is under control of the operator, as a primary outcome measure. Although not ideal, it allowed us to make a meaningful estimate of the number of patients who would need to be included in the study. It is possible that we might have overcome the variability by completing a much larger study, but we wanted to focus on those factors that might be easily modifiable by the op...

The use of flat-panel detector (FPD) systems in TV equipment for gastrointestinal tract examination is increasing. The use of FPD systems is believed to reduce the exposure dose. When our institution changed its TV equipment from an image intensifier (GE;MS90Tj) system to an FPD (Shimadzu;SONIALVISION safire DAR-3500) system, we measured the doses produced and carried out a comparative examinat...

Breast cancer incidence data were analyzed from three populations of women exposed to ionizing radiation: survivors of the Hiroshima and Nagasaki atomic bombs, patients in Massachusetts tuberculosis sanitoria who were exposed to multiple chest fluoroscopies, and patients treated by X-rays for acute postpartum mastitis in Rochester, New York. Parallel analyses by radiation dose, age at exposure,...

This article discusses the dose to the operator and radiation protection in computed tomographic fluoroscopy (CTF)-guided intervention. One of the major limitations of CTF is excessive radiation exposure to the operator, in particular, to his or her hands. Therefore, we developed biopsy needle-holders that permit the operator to manipulate the needle without placing his or her hands in the dire...

In this case report, we look into the implant procedure of a single-lead ICD with floating atrial sensing dipole in a pregnant woman, without using fluoroscopy. This system benefits the proper positioning of the lead. This is possible thanks to the simultaneous display of both the atrial and ventricular dipoles on the electro-anatomical mapping system. This technique may be taken into considera...
