Abdominal imaging
-
To investigate the feasibility, strategy, and long-term outcome of percutaneous recanalization for combined-type Budd-Chiari syndrome (BCS). ⋯ Percutaneous recanalization is suitable for most combined-type BCS patients. Treatment strategy can be made according to the situation of AHV. If the patient has the patent AHV, single IVC recanalization is enough. Otherwise, combined IVC and HV recanalization should be performed.
-
To compare radiation dose and image quality in regular, low, and ultralow-dose CT protocols, and to evaluate diagnostic performance of low-dose CT for urolithiasis. ⋯ The knowledge-based IR can provide a better quality image while reducing radiation exposure under the same protocol. Furthermore, the diagnostic performance of the low-dose CT protocol is comparable to the regular dose scan.

Comparative Study
Low-tube voltage 100 kVp MDCT in screening of cocaine body packing: image quality and radiation dose compared to 120 kVp MDCT.
The aim of this study was to evaluate the impact of a reduced tube potential (100 kVp) for non-enhanced abdominal low-dose CT on radiation dose and image quality (IQ) in the detection of body packing. ⋯ Low-tube voltage 100 kVp MDCT with automated tube current modulation in screening of illegal drugs leads to a diagnostic IQ and significant dose reduction compared to 120 kVp low-tube voltage protocols. Despite lower radiation dose, liquid and solid cocaine containers retain high attenuation and are easily detected.
