Diagnosis of several gastrointestinal diseases in sheep with B-ultrasound
Belly distension of sheep: The left skin of sick sheep is rapidly swollen due to excessive gas in the rumen, with drum sounds on percussion, strong elasticity on palpation, dull spirit, loss of appetite, restlessness in rising and lying, arching the back and moaning, looking back at the abdomen. In severe cases, the breathing speeds up and death from exhaustion occurs. When diagnosing this disease, it is also possible to use B-ultrasound to check the rumen status of sheep for auxiliary diagnosis. Prevention: Feed less fermentable succulent feed to prevent sheep from eating spoiled or poisonous forage and poisonous insects, and often use B-ultrasound to check the rumen status of sheep. Treatment: rumen massage, gavage with anti-fermentation agent, rumen puncture to exhaust gas, and rumen peristalsis drugs attached. B-ultrasound examination for sheep can be used after treatment. Abdominal relaxation in sheep: caused by decreased peristaltic function of the anterior stomach, clinically manifested as indigestion. The cause of the disease is long-term feeding of poor quality and indigestible forage, or too much concentrate and too little grass, which makes the gastrointestinal burden too heavy to adapt to, and even insufficient drinking water, improper feeding methods, and mutations in forage can also...

What you need to know about ultrasonography?
Abdominal ultrasonography: Abdominal ultrasound is the most common, usually what we call liver, gallbladder, pancreas, and spleen examinations. Applicable to: Abdominal screening for abdominal pain, bloating, abdominal discomfort, etc., and inspections for certain organ diseases. Requirements: Fasting for more than 8 hours. Fasting means not eating or drinking anything. I often encounter patients who say that they have not eaten, and if they ask again, they will tell you that they drank some milk or a bowl of soy milk, which is not acceptable. (Of course, if you need to take medicine, you can drink a little water). Urinary tract ultrasonography: Ultrasound of the urinary system includes examination of the kidneys, ureters, bladder, and prostate in males. It is mainly suitable for the screening of tumors, stones, abnormal development of the urinary system, and abnormal urine routine findings. Requirements: Simple kidney examination does not need to be prepared. The bladder, ureter, and prostate need to be filled. You can drink 1000 to 1500 ml of water (or various beverages) 1 to 2 hours before the examination, and hold back the urine after drinking the water. It is difficult to quantify the degree of holding back the urine. It feels the...

Knowledge of veterinary B-ultrasound probe
A veterinary ultrasound probe is a device that converts one form of energy into another. In ultrasound, sound waves are generated by electrical charges, causing a piezoelectric disk inside the probe to vibrate. Piezo is derived from the Greek word meaning “to press”. Piezoelectric materials are piezoelectric materials, such as quartz, that change shape and size when exposed to an electric field. Piezoelectric crystals are usually cylindrical, 1 to 2 cm wide and 1 mm thick. The current causes the crystal to expand and contract depending on the polarity of the current, and this vibration produces sound waves. The crystals also act as receivers, converting reflected sound waves into electricity, which in turn is converted into modified radio waves that produce images on the screen. Other piezoelectric substances include barium titanate, lithium sulfate, and lead zirconate. Barium titanate is most commonly used. Sensors of various frequencies produce different penetrations. The frequency range is 1-25 MHz; frequencies of 3.5, 5.0, and 7.5 MHz are most common. High frequency probes produce short high frequency wavelengths (i.e. 7.5 MHz) and scan shorter distances with sharper resolution, low frequency probes produce longer wavelengths with greater beam penetration. Although these probes can scan at greater...

Do you know these knowledge about ultrasonography?
1. Is ultrasound examination harmful to the body? The medium used in ultrasonic examination is ultrasonic waves, which have no ionizing radiation. The conduction in the human body utilizes the characteristics of sound waves, just like our speaking voice. Ultrasound examination is a very safe examination, so it is commonly used in obstetrics for fetal examination. 2. Is color ultrasound more advanced than B ultrasound? The full name of color ultrasound is color Doppler ultrasound. B ultrasound is B-type two-dimensional ultrasound. Color ultrasound is based on B-type two-dimensional ultrasound with the addition of color Doppler inspection function. It can check the blood supply of organs and blood flow spectrum. Whether the shape and blood flow velocity are normal, so color Doppler ultrasound is more widely used in clinical practice. 3. What is the substance applied during the ultrasound examination? During an ultrasound examination, the doctor will apply a layer of jelly-like substance on the examination site. It is called a coupling agent, which is a water-soluble liquid that isolates the air and allows the ultrasound probe to be in better contact with the skin. The conduction of sound waves ensures the inspection effect, without any poisonous effect, just wipe it...

Summary of basic knowledge of ultrasound(part four)
Section 9 Superficial Organ Ultrasonic Examination Measurement Methods and Normal Values Thyroid Ultrasound Measurement Methods (1) Thickness (anterior-posterior diameter) and width (left-right diameter) measurement of the thyroid gland 1. Standard measurement section: in a series of cross-sections of the thyroid gland, the thickest and widest part of the thyroid parenchyma is selected as the standard section, and the pressure of the probe should be as light as possible. 2. Measurement location: respectively selected at the edge of the hyperechoic line of the capsule at the thickest and widest parts of the thyroid gland. 3. Normal adult reference value (cm): the thickness of the left and right leaves is 1.5~2.0cm, The width is 2.0~2.5cm, and the thickness of the isthmus is less than 0.5cm. (2) Measurement of the long diameter (upper and lower diameter) of the thyroid gland 1. Standard measurement section: In a series of longitudinal sections of the thyroid gland, the longest part of the thyroid parenchyma is selected as the standard section, and the pressure of the probe should be as light as possible. 2. Measurement locations: respectively selected on the edge of the hyperechoic line of the capsule at the longest part of the thyroid gland. 3....

Summary of basic knowledge of ultrasound(part three)
Section 7 Measurement methods and normal values of gynecological ultrasonography one. Uterus Three diameters need to be measured, the longitudinal diameter, transverse diameter and anteroposterior diameter of the uterus. 1. Uterine longitudinal diameter (upper and lower diameter) measurement; (1) Measurement section: Sagittal section of the uterus. It is necessary to clearly show the symmetrical sections from the fundus of the uterus to the internal os of the cervix, the muscle layer, and the front and back layers of the endometrium. (2) Measurement location: Uterine body: the distance between the outer edge of the uterine fundus and the internal os of the cervix. Cervix: the distance between the internal os of the cervix and the external os of the cervix. (3) Normal value: palace body 5.0 ± 1.0cm. Cervix 2.5-3.0cm. 2. Measurement of the transverse diameter (left and right diameter) of the uterus: (1) Measurement section: coronal section of the uterus. The uterus needs to be transected, and the measurement is performed at the middle of the uterine body and when the image shows the largest elliptical section (not at the place where the image is triangular). (2) Measurement position: the maximum left and right diameter passing through the uterine body....
