Abstract
The invention relates to a method of intravenous pyelography and CT TLC scanning and multiple plane reconstructing, using high dose of low intravenous pyelography, spiral CT TLC scanning and multiple plane reconstructing. The said method comprises the following steps: injecting 40 ml 60% meglumine diatri-zoate from elbow vein (containing 10 mg 654-2); after about 10 min, plain scanning and positioning the image when the contrast agent of urinary system reaches peak; confirming scanning baseline; performing 29 layers of spiral CT TLC scanning; multiple plane reconstructing the image using computer image processing system. The patient performs inspection without wound and with low cost using the method.
Description
Technical field:
The present invention relates to the method for a kind of intravenous urography and CT thin slice scan and multiplanar reconstruction.
Background technology:
Renal pelvis, the ureter portion of dividing a word with a hyphen at the end of a line is narrow more rare, mainly shows as hydronephrosis clinically, is in the tube wall due to pathological changes or the urethra road pressurized.Because the ureter structure is tiny, can only see hydronephrosis after it is narrow, and stenosis does not have and directly levies picture and show, so ultrasonicly can not know the lesions showed district; And common CT examination also can only be understood nephrydrotic general form structure, and its image does not have seriality, and full the generation well of contrast-agent-free contrasts; Single conventional intravenous urography inspection, when hydronephrosis since contrast concentration descend cause develop light, and image overlap.Therefore, the three all is difficult to clear and definite lesion nature, determines renal pelvis, ureter divide a word with a hyphen at the end of a line portion narrow length and degree.
Summary of the invention:
Purpose of the present invention just provides the method for a kind of intravenous urography and CT thin slice scan and multiplanar reconstruction.
Purpose of the present invention can realize by following scheme.
The present invention adopts a heavy dose of low intravenous urography, spiral CT thin slice scan and multiplanar reconstruction three to combine, and the low intravenous urography of opening of described heavy dose is meant that contrast agent dosage is increased to 40ml and includes 654-210mg; Described CT thin slice scan is meant that bed thickness, interlamellar spacing are 3mm, and timebase is that the center is total to 29 layers of continuous sweeps with the narrow; Described multiplanar reconstruction is meant crown position, sagittal plain, the multi-faceted reconstruction of loxosis.
Its concrete operations technology is as follows: inject 60% general shadow dried meat amine 40ml through ulnar vein, wherein include 10mg654-2, after about 10 minutes when urinary system contrast agent peaking unenhanced location image, determine timebase then, carry out 29 slices spiral CT thin slice scan, finish back appliance computer image processing system and carry out the multiplanar reconstruction image.
This method does not have the wound expense when disease is gone into to check low.
Claims (1)
1. the method for an intravenous urography and CT thin slice scan and multiplanar reconstruction, it is characterized in that adopting a heavy dose of low intravenous urography, spiral CT thin slice scan and multiplanar reconstruction three to combine, the low intravenous urography of opening of described heavy dose is meant that contrast agent dosage is increased to 40ml and includes 654-2 10mg; Described CT thin slice scan is meant that bed thickness, interlamellar spacing are 3mm, and timebase is that the center is total to 29 layers of continuous sweeps with the narrow; Described multiplanar reconstruction is meant crown position, sagittal plain, the multi-faceted reconstruction of loxosis, its concrete operations technology is as follows: inject 60% general shadow dried meat amine 40ml through ulnar vein, wherein include 10mg654-2, after about 10 minutes when urinary system contrast agent peaking unenhanced location image, determine timebase then, carry out 29 slices spiral CT thin slice scan, finish back appliance computer image processing system and carry out the multiplanar reconstruction image.
