The role of color histograms in predicting the prognosis of patients with digestive tract adenocarcinoma.

Objectives: To establish the correlation between the degree of vascularisation detected using power Doppler ultrasonography in digestive tract adenocarcinoma and the prognosis of these patients.

Material And Method: Ultrasonography was performed in 45 patients diagnosed with digestive tract adenocarcinoma (16 stomach-35.6%, 6 cecum and ascending colon-13.

The sensitivity of transabdominal ultrasound in the diagnosis of ureterolithiasis.

Objectives: The ultrasonographic diagnosis of renal lithiasis colic is suggested by the existence of hydronephrosis, but the certainty is given by the direct visualization of the ureteral calculus. The aim of this study is to assess the performance of ultrasound in identifying ureteral calculi compared to other imaging methods (abdominal X-ray, urography and computed tomography).

Material And Method: We performed ultrasonographic examination (one or multiple examinations) in 217 patients with renal colic and ureterolithiasis.
