Multiparametric analysis of preoperative lymphatic mapping with the use of combined deep plus superficial radiotracer injection technique in early breast cancer.

Objectives: According to literature, combined tracer injection techniques seem to be the more powerful choice to eliminate technical and patient-related limitations. In this study, we analysed the quantitative performance parameters of combined deep plus superficial radiotracer injection and their correlation with a set of clinical, pathological and technical factors.

Methods: One hundred and sixteen women who underwent preoperative sentinel lymph node (SLN) mapping were studied prospectively.

Reproducibility of technetium-99m mercaptoacetyltriglycine clearance in patients with impaired renal function.

Background: The aim of this study was to determine the reproducibility of technetium-99m mercaptoacetyltriglycine (99mTc-MAG3) clearance in patients with a 99mTc-MAG3 clearance below 100 ml/min/1.73 m2.

Methods: Two separate multi-sample clearance studies were performed in 16 patients at a 1 week interval.
