  • Title: Aortic and renal atherosclerotic calcifications seen on computed tomography of the spine. A positive predictor of hypertension.
    Author: Moynahan K, Yoshino MT.
    Journal: Invest Radiol; 1993 Sep; 28(9):811-3. PubMed ID: 8225886.
    Abstract:
    RATIONALE AND OBJECTIVES: This study was undertaken to determine if there is an association between hypertension and aortic or renal atherosclerotic calcifications seen on computed tomography (CT) of the spine. METHODS: The lumbar CTs of 93 sequential patients were evaluated without knowledge of their blood pressures. Aortic and renal atherosclerosis was graded on a scale of 0-3. The patients' charts were reviewed for the presence of hypertension and diseases that might cause hypertension. RESULTS: Sixty-five patients had atherosclerotic calcifications. Forty-four of these were hypertensive. Logistic regression analysis revealed that calcifications in the left renal artery (P = .003), the right renal artery (P = .010) and the abdominal aorta (P = .001) are statistically significant positive predictors of hypertension. Renal artery calcifications are better predictors of hypertension than aortic calcifications. CONCLUSIONS: Renal and abdominal aortic calcifications are significant radiographic findings in lumbar spine CT examinations and their presence should be routinely included in the radiographic report.
