CT density of liver after amiodarone administration was significantly higher than that before administration. No correlations were identified between cumulative dose of amiodarone and either liver density after administration or density change of liver. Amiodarone usage should be checked when radiologists identify high density of the liver on CT.

Concurrent radiotherapy with Transcatheter Arterial Infusion (TAI) chemotherapy is reportedly effective in curing locally advanced head and neck cancer. However, the effectiveness and safety of using TAI with palliative or salvage intent after radiotherapy combined with systemic intravenous chemotherapy (IV-CRT) is not well known. Herein, we describe two cases using TAI palliatively for locally advanced residual tongue cancer after IV-CRT, where tumor reduction or tumor progress inhibition could be achieved, thereby improving or maintaining the patients’ quality of life without severe toxicities. These cases indicate the effectiveness and safety of using TAI palliatively for locally advanced tongue cancer. Further, we have combined a literature review with the description of these cases.

In the original publication, in Abstract, the second sentence of "Results" should read as:Whereas in FWDCs, a significantly larger volume and lower density of fluid in the paranasal sinuses (P = 0.0195 and P = 0.0104, respectively), lower density of fluid in the central airways (P = 0.0077), lower stomach content density (P = 0.0216), lower density in the left atrium (P = 0.0029), and a difference of density between the atria (P = 0.0019) were observed.In Table 3, in last line, the numbers of fresh water drowning and the P value were incorrect. The corrected Table 3 is given in this Correction.In Results section, under the heading "CT number of the right and left atria", the third sentence should read as:The difference in CT number between the bilateral atria (LA minus RA) was smaller in the FWDCs (0.9 ± 10.9 HU) than in the SWDCs (14.4 ± 10.8 HU, P = 0.0019).The original article can be found online at https ://doi.
