Aims and objectives
To determine the prevalence and associated factors of diffuse idiopathic skeletal hyperostosis (DISH),
to calculate the interobserver agreement for computed tomography (CT) based diagnosis of DISH based upon Resnick criteria and reporting rate of DISH on routine CT imaging.
Methods and materials
This retrospective cross-sectional study was approved by the institutional review board (IRB) of our institute with a waiver of the requirement for patient’s informed consent. Population All patients of either gender aged 30 years or above underwent CT chest,
abdomen and pelvis for different abdominal,
pelvic and urological conditions at our hospital during January 2017 to March 2017 were included whereas patients with history of trauma or road traffic accident,
already diagnosed with diffuse...
Out of total 214 patients,
majority of the patients were males (n=138,
The median age of the patients was 60 (50.75-65.0) years. The prevalence of DISH was found to be 29.9%.
Gender distribution showed that DISH was 35.5% prevalent in males and 19.7% prevalent in females. Vertebral fracture was observed in 10 (4.7%) patients.
Out of these 10 patients,
“D12” fracture site was observed in majority of the patients (n=4,
followed by “L1” in 3 (30%),
“D12 and L1 both”...
In the present study,
by utilizing the sagittal reconstruction images of CT chest,
abdomen and pelvis,
the prevalence of diffuse idiopathic skeletal hyperostosis was surprisingly higher than the previous plain radiograph based or CT based studies.
A previous CT based study conducted on Japanese population showed slightly lower prevalence as compared to our study .
previous studies based on plain radiographs have reported much lower prevalence [3-6].
We believe that this high...
