Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | For Cause | For cause biopsy to evaluate a recent rise in serum creatinine.~Optison~Ultrasound (US): A routine diagnostic and color-Doppler US. A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow.~Contrast-enhanced ultrasound (CEUS): Contrast-enhanced ultrasound (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Ultrasound contrast agents rely on the different ways in which sound waves are reflected from interfaces between substances. This may be the surface of a small air bubble or a more complex structure. | 2 | 20 | EG000 |
| Group 2 | Surveillance | Surveillance biopsy done after transplant mostly looking for subclinical rejection.~Optison~Ultrasound (US): A routine diagnostic and color-Doppler US. A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells.
