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.

Splenic artery pseudoaneurysm (SAPA) is a relatively infrequently encountered but clinically important vascular change, because it carries a high risk of rupture that warrants prompt treatment regardless of its size. Thus, sufficient knowledge is indispensable when seeing chronic pancreatitis patients or post-traumatic patients. Here, we report two such cases. The first case was a 52-year-old woman known to have chronic pancreatitis who presented with hematemesis and hemodynamic instability in which X-ray computed tomography (CT) and color Doppler sonography (CDS) had difficulty visualizing slow blood flow in SAPA, but superb microvascular imaging (SMI) clearly demonstrated the slow blood flow in SAPA, prompting our therapeutic decision to perform rapid embolization. The second case was a 51-year-old woman with post-traumatic SAPA in which 3D SMI enabled us to understand more clearly the topographic relationship between multiple SAPAs as compared with conventional US, leading to a decision to provide immediate surgical treatment. SMI was thought to provide a new insight into the US diagnosis of SAPA. When examining patients suspected of having a SAPA, SMI is an indispensable diagnostic tool at present.

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.

We present two patients who experienced massive hemoptysis during follow up after pulmonary artery embolization with coils for Pulmonary Arteriovenous Malformations (PAVM). The treated PAVMs responsible for hemoptysis were supplied from the bronchial artery. Hemoptysis was controlled for a short time by bronchial artery embolization with n-butyl-2-cyanoacrylate in case 1 and gelatin sponge in Case 2. Thereafter, however, one patient (Case 2) died of recurrent massive hemoptysis. These cases may indicate that bronchial artery supply is the cause of both hemoptysis and reperfusion of treated PAVMs.
