Comparative Study
The role of ultrasonography in the imaging of body packers comparison with CT: a prospective study.
This study investigated the sonographic properties of drug packets containing narcotic drugs and the diagnostic role of ultrasonography in detecting body packing in comparison with CT. ⋯ Ultrasonography was found to have a high sensitivity but a low specificity in suspected cases. A negative ultrasonography cannot rule out the diagnosis of body packing. However, it may be preferred as the initial imaging method or for follow-up of suspected cases as a radiation-free, easy-to-use, and inexpensive technique.

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.
