Transizyonel vertebra tanısında grafilerin birlikte değerlendirilmesi

Abstract

AİM: Full vertebral scanning and counting from C2 inferiorly is the gold standard for the lumbosacral transitional vertebrae (LSTV) diagnosis. We aimed to investigate the use of a posteroanterior chest radiograph (CRXPA) and direct urinary system graph (DUSG) combination, which would provide lower dose radiation exposure in LSTV diagnosis.
 MATERIALS & METHOD: CRX PA and DUSG of 327 patients were examined by 2 radiologists. Both of the x-ray graphs have been interpreted by the radiologist to detect existing LSTV. Scoliosis graphs were conducted of all 327 patients to detect LSTV
 RESULTS: The performance accuracy of DUSG for the diagnosis of LSTV, we have observed that it provided true positive results in 117 of the 120 subjects and false-negative in 3 subjects. It could detect 163 of the 207 subjects as true negative and the remaining 44 individuals as false positive. When we have evaluated the diagnostic performance of DUSG and CRX PA together we have observed that it provided true positive results in 119 of the 120 subjects and false-negative in 1 subject. It could detect 167 of the 207 subjects as true negative and the remaining 40 individuals as false positive.
 CONCLUSION: The accurate diagnosis of LSTV is highly important as any misleading information can lead to inappropriate surgery or invasive procedure. The sensitivity of interpretation of CRX PA and DUSG together has been found as 97.6% and the specificity as 80.6%.
