diagnostic purpose

(1)Patients aged 20 years and over
(2)Patients who agrees with this study in writing.
(3)Patients who have a hip surgery (Arthroplasty, Artificial head insertion,Open osteosynthesis,Osteotomy).

(1)Patients who are currently pregnant or may be pregnant.
(2)Patients who cannot move to the X-ray room on their own.
(3)Patients who cannot catch their breath.
(4)Patients who are judged to be inappropriate by the investigator and the investigator.
(5)Patients who cannot perform contrast-enhanced CT or dynamic X-ray due to some postoperative complications

Both

Pulmonary embolism

Dynamic Digital Radiography

Agreement between diagnostic results of pulmonary embolism on contrast-enhanced CT and pulmonary blood flow mapping images.

(1)Comparison of presence of pulmonary embolus between PH-mode and D-dimer.
(2)Comparison of pulmonary blood flow before and after surgery. Investigation of the effects of surgery other than pulmonary embolism.
(3)Differences between the results of PH-mode with and without the addition of the cardiac region. In addition, a comparison with contrast-enhanced CT is included.
