[Percutaneous computed tomography-guided biopsy in spinal diseases]

Spinal diseases often require precise diagnostic tools to guide treatment decisions. While traditional biopsy methods have been used, newer imaging-guided approaches are emerging. Prior research has shown that percutaneous biopsy can be effective in various anatomical regions. However, the diagnostic accuracy of CT-guided spinal biopsy remains unclear. This uncertainty drives the need for studies evaluating its reliability. Establishing the diagnostic yield of such procedures is essential for clinical decision-making. No prior work had resolved the accuracy of CT-guided spinal biopsy in a large cohort. This gap motivated a focused assessment of its performance in spinal disease settings.

This study aimed to evaluate the diagnostic accuracy of CT-guided percutaneous spinal biopsy. The specific problem addressed was the lack of data on how reliably this method can provide histopathologic samples. The motivation stemmed from the need to confirm whether CT guidance improves biopsy outcomes in spinal conditions. The authors sought to determine the success rate of tissue sampling across different spinal segments. They also aimed to assess whether the method could support treatment planning for spinal neoplasms or inflammatory conditions. The study focused on diagnostic reliability rather than procedural safety. By analyzing a cohort of patients, they intended to quantify the diagnostic yield of the technique. Their goal was to provide evidence for the role of CT-guided biopsy in spinal disease management.

The study involved 74 patients who underwent CT-guided percutaneous spinal biopsy from 1990 to 1992. The sample included 50 men and 24 women with an average age of 47. The primary tool used was computed tomography for procedural guidance. The researchers evaluated the accuracy of the biopsy in diagnosing spinal lesions. They categorized results based on the spinal segment and lesion type. Histopathologic analysis of the collected tissue was the main outcome measure. The study tracked cases where tissue was insufficient for diagnosis. No additional imaging modalities were used for comparison in this analysis.

The overall diagnostic accuracy of CT-guided percutaneous spinal biopsy was 86%. In 14% of cases, the tissue obtained was insufficient for histopathologic diagnosis. The accuracy varied depending on the spinal segment and lesion type. The highest success rates were observed in specific lesion categories. These findings suggest that CT guidance improves tissue sampling in spinal procedures. The method proved reliable for diagnosing both neoplastic and inflammatory conditions. The results were consistent across a range of patient demographics. The study provides quantitative evidence for the diagnostic yield of this technique.

The authors concluded that CT-guided percutaneous spinal biopsy is a valuable diagnostic tool. They propose that it supports accurate histopathologic diagnosis of spinal lesions. The method is described as simple, reliable, and definitive for diagnostic purposes. The findings suggest that this technique aids in planning treatment for spinal neoplasms. The diagnostic accuracy of 86% supports its use in clinical settings. The study emphasizes the importance of tissue sampling for treatment decisions. The authors suggest that this method is particularly useful in inflammatory and metabolic spinal diseases. Their conclusions are based on the observed success rates in the cohort studied.
