Incorrect Correct 2) Soft X-Ray Radiography of the Achilles Tendon Achilles tendon hypertrophy should be evaluated using soft X-ray radiography. Positioning is performed so that the lower leg bones and sole of the foot form a 90-degree angle, and radiation is administered so that the X-ray enters the center of the lateral malleolus from the side of the foot. The imaging distance should be 120 cm, and the imaging conditions should be 50 kV and 5.0 mA. When the greatest dimension is ≥ 9 mm,

... rophy is diagnosed. Conducting the evaluations using ultrasonography is possible, although it has not yet been standardized. 2) X-Ray Radiography of the Achilles Tendon Achilles tendon hypertrophy should be evaluated using low-voltage radiography. Positioning is performed so that the lower leg bones and sole of the foot form a 90-degree angle, and radiation is administered so that the X-ray enters the center of the lateral malleolus from the side of the foot. The imaging distance should be 120 cm, and the imaging conditions should be 50 kV and 5.0 mAs, e.g. 100 mA×0.05 sec or 50 mA× 0.1 sec when using a digital system. When the greatest dimension is ≥ 9 mm, then hypertrophy is diagnosed. Conducting the evaluations using ultrasonography is possible, although it has not yet been standardized.
