A convex array probe is usually used for kidney examination.
The quality of kidney images obtained from the back is better than that of lateral scanning.
C. the renal capsule is clear and smooth.
D. the renal sinus area showed strong echo.
2. The description of renal cyst is wrong:
A. Single renal cyst is also called solitary renal cyst.
B. Multiple renal cysts are also called polycystic kidneys.
C. complex renal cysts can have sediment-like echoes.
D. Complex renal cyst is also called atypical renal cyst.
3. The following descriptions about the ultrasonic manifestations of renal cell carcinoma are wrong:
A. The incidence of renal cell carcinoma in men is higher than that in women.
B: It can be seen that there is a solid mass in the kidney, which is round or oval, and a few masses can be irregular.
C the small mass is hyperechoic, the large mass is hypoechoic, and the internal echo can be uniform or uneven.
D: There is no increase in blood flow in D:CDFI mass, so the possibility of renal cancer can be ruled out.
4. The ultrasonic manifestations of the following renal tuberculosis are wrong:
A. The earliest renal tuberculosis can be normal.
B. cystic anechoic area can be seen in the kidney.
The inner wall of C capsule cavity is smooth, and the echo of posterior wall is enhanced.
D) Strong echo with large sound shadow can be seen in the kidney.
5. The description of bladder ultrasound is wrong:
A bladder tumor should be differentiated from prostatic hyperplasia.
B. The base of bladder tumor is often wide, the tumor size is different, the surface is not smooth, and it does not move with body position.
Reverberation artifacts can be seen in the anterior wall of bladder.
D. There is no need to fill the bladder during abdominal and rectal scanning.
6. The mistake of prostatic hyperplasia lies in:
A. it is most important to increase the front and rear diameters.
B. it is often manifested as nocturia and dysuria.
C. Not just the transition zone
D. the blood flow of the external gland is rich.
Reference answer and analysis
1. Answer B. Analysis: The quality of kidney images obtained in lateral position is better than that in back scan. Check the right kidney in left lateral position, and check the left kidney in right lateral position. Back scanning will be affected by ribs, which is generally used for patients with difficulty in abdominal scanning. Therefore, choose B in this question.
2. Answer B. Analysis: There are two or more cysts in the kidney called multiple renal cysts, and the prognosis is generally good. Even multiple cysts in both kidneys are mostly benign, which is different from polycystic kidney. Polycystic kidney is a congenital bilateral renal dysplasia, and the renal sinus area is compressed and deformed by most vesicles, which is not even clear. Therefore, choose B in this question.
3. Answer D. Analysis: CDFI examination of renal cell carcinoma shows various manifestations. Color blood flow in tumor can be rich, rare or even no signal, with peripheral blood flow signal and rich spherical color blood flow signal. Therefore, choose D in this question.
4. Answer C. Analysis: At the earliest stage, the focus of renal tuberculosis was small, self-healing, and the ultrasonic manifestations were completely normal; Renal tuberculosis can form a cavity connected with renal calices, showing an echo-free area; In patients with renal tuberculosis, the cystic mass has irregular shape, thick and rough cystic wall, sometimes uneven thickness or even jagged shape, uneven patchy strong echo on the inner wall of the capsule, cloud-like echo in the anechoic area in the capsule, and strong echo with sound shadow when calcified. When there is a renal cyst, option C is the most obvious. Therefore, this question chooses C.
5. Answer D. Analysis: When scanning abdomen and rectum, the bladder should be moderately filled, which can clearly show that the bladder wall is neat and smooth, the thickness is uniform, and the mucosa, submucosa and muscularis are thin and the layers are clear. Therefore, choose D in this question.
6. Answer D. Analysis: BPH is a benign lesion, mostly located in the internal gland (transitional zone) and a few in the external gland (peripheral zone). Compared with normal gland tissue, the blood supply of hyperplastic tissue is increased, so the inner gland can see more blood flow.
