DRS was performed according to a standard procedure. A patient was placed in the supine position with a gamma camera detector (GE Infinia Hawkeye 4) in the posterior projection. Image acquisition was started at the time of intravenous injection of 111 MBq of 99m Tc-EC. A sequence of 60 images was acquired of 20 seconds each. Counts were stored in a 128 × 128 matrix. The camera detector, equipped with a LEHR collimator, was positioned so that its field of view covered -in addition to kidneys -also a heart.

Preoperative SPECT/CTs were obtained within 48 h of admission to the hospital using a dual-headed gamma camera (Infina, Hawkeye 4, GE Healthcare, Milwaukee, WI, USA) equipped with low-energy high-resolution (LEHR) collimators. The SPECT data were acquired with 60 stops over 180 at 12 s per stop using a 128 × 128 matrix within three to five hours post-injection of 1100 MBq Tc-99 m HDP. The CT acquisition was performed at 140 kvp and 2.5 mA using a 512 × 512 matrix and a 5-mm slice thickness (pitch 10, interval 2.95 mm). The SPECT images were reconstructed using an iterative algorithm provided by the manufacturer to reduce starring artifacts by bladder activity. And attenuation correction was done with CT-derived attenuation maps.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
