   is not necessarily more difficult to check. The free thrombus may be small or attached to the wall, which makes it difficult to distinguish. If you go to the root cause, you may be able to find a relatively large block. The damaged heart will definitely show certain changes in the anatomical structure.

  With this idea as a guide, the doctor in the CT room must scan a little more carefully when scanning the key areas of the patient.

  CT scanning speed is not slow, but it takes time for the doctor to read the film. Not long after, Xiao Shugang was pushed out of the examination room. Xie Wanying came out and said hello to her cousin and sister-in-law, and asked them to go to the inpatient department first, and then she stayed in the office to read the film with Teacher Xu.

  Because of the fine scan, hundreds of images are displayed on the computer, and it is not easy for doctors to read and pick out the thorns one by one.

  Xie Wanying and Dr. Zhao sat next to Mr. Xu and the three read together. To be honest, if you are not used to this job, at first glance at these hundreds of images that look very similar, you will really doubt that your eyes will be blind.

   "This is a boundary ridge, not a thrombus or a tumor." Dr. Xu pointed to a small gray area that looked like an abnormal bulge in the white area on the film.

The    bordering crest is the fusion line between the original atrial appendage and the vena cava, located between the right atrial appendage and the vena cava, and continues from the superior vena cava to the inferior vena cava. In the report of the doctor in the CT room of the Provincial People\'s Hospital, this was used as an edge ball. It was Dr. Xu who saw at a glance that the report was suspected of being partly fabricated.

   Enhanced CT was done, and it seemed that the thrombus in the right atrium was difficult to find. Look again for the ventricle that was highlighted in the discussion just now.

   Suspected thrombus in the right atrium, and the right ventricle is the next focus. Anatomically, the right ventricle can be divided into three parts, one is the inflow tract, the tricuspid valve entrance and its accessory structures. The second is the outflow tract, a tubular structure such as the conus arteriosus that supports the pulmonary artery lobes. The third is the muscle trabeculae in the middle of the upper two.

   When the heart is impacted by an external force, it may first be manifested as damage to the ventricular wall.

   The ventricular wall of the right ventricle itself is very thin, only 3 mm. Doctors need to be more patient.

  If the general outline of the heart structure is normal, it is best to do an ultrasound examination to see if there is a problem with the movement function. An echocardiogram can check valve activity and blood flow in the heart. From CT, only the static structures of the tricuspid valve and the pulmonary valve can be identified.

  Three pairs of eyes are like a needle in a haystack looking for a hole in hundreds of images.

   Veteran doctors read a lot of films, and the angle of the brain when looking at the images rotates faster with the film. Young doctors may not be able to keep up with this rhythm.

   Dr. Zhao rubs his eyes from time to time. At the moment when he is studying imaging, he is not only looking at his eyes, but also confused by his brain. To this end, he glanced at Xie classmate beside him.

  Xie Wanying followed the teacher with her eyes fixed, her expression very calm and meticulous.

   Teacher Xu is fast. Like their top three top specialists in the country, the CT room has a huge workload every day. When encountering difficult cases, doctors may spend more time and energy to study them, but if they can\'t find them, it will be ineffective to give them more time to study. It is impossible to give a year and a half to do research. It\'s not that the doctor can\'t wait, it\'s the patient\'s condition that can\'t wait. It\'s just that today\'s patients are more difficult to find, and Dr. Xu can\'t take care of giving lectures to students, and his brows are slightly anxious while staring at the images.
