A postero-anterior teleoroentgenogram of the chest is primarily a "scout" film, and diagnosis based solely on such an examination is often little more than guesswork. However, this film serves admirably in detecting most lesions, and aids in determining what additional studies need to be performed. Unless the clinical or roentgen diagnosis is evident, one should then proceed with further roentg...

The obligatory use of fluoroscopy for placement of epidural steroids is controversial. Proponents of the use of fluoroscopy cite studies that report up to 35% rates of inaccurate placement of epidural needles without the aid of fluoroscopic imaging. This case study presents a situation in which a loss-of-resistance technique resulted in an inadvertent discogram.

PURPOSE Alcohol is not used directly to the vascular lesion without mixing with the contrast agent because alcohol itself cannot be seen on the fluoroscopy. Since we have used alcohol for the venous malformations in the head and neck area, we realized that alcohol can be safely and effectively used without using fluoroscopy. We present the method of direct sclerotherapy using absolute alcohol w...

BACKGROUND The sacroiliac (SI) joint is frequently the primary source of low back pain. Over the past decades, a number of different SI injection techniques have been used in its diagnosis and therapy. Despite the concerns regarding exposure to radiation, image-guided injection techniques are the preferred method to achieve safe and precise intra-articular needle placement. The following study ...

Retained intravascular foreign body is a well-known complication of central venous access placement in children as well as adults. Most of these foreign bodies are radio-opaque and hence are removed under fluoroscopy guidance. In our case, we describe the removal of an intracardiac radiolucent foreign body in an infant utilizing a combination technique - transesophageal echocardiogram and fluor...

Laryngopyocele recurrence after initial surgical resection is a very rare occurrence. We present a case of recurrent laryngopyocele in which CT fluoroscopy-guided hookwire placement was used to facilitate resection. In this article, we illustrate the imaging findings of laryngopyocele, review the approach to management, and describe the CT fluoroscopy-guided hookwire placement procedure.

OBJECTIVE The purpose of this study was to prospectively evaluate the clinical utility and accuracy of intraoperative three-dimensional fluoroscopy as an adjunct for the placement of a complex spinal instrumentation. METHODS The Siemens Iso-C three-dimensional fluoroscopy unit in the combination with the Stealth Treon computer volumetric navigational system was used. A total of 279 spinal ins...

BACKGROUND Some symptomatic degenerative conditions of the lumbar spine may be treated with spinal fusion if conservative treatment has failed. The minimally invasive technique of transforaminal lumbar interbody fusion (MIS TLIF) is increasingly used but has been found to generate increased radiation exposure to the patient and staff. Modern three-dimensional (3D) C-arm devices are capable of p...
