  • Usefulness of computed tomography for hospitalized adult patients with fever to investigate cause of fever: single-center, retrospective cohort study

    Hamabe F., Terayama T., Mikoshi A., Murakami W., Yamada K., Soga S., Shinmoto H.

    Japanese Journal of Radiology (Japanese Journal of Radiology)  39 ( 8 ) 802 - 810 2021.08

    ISSN  18671071

     View Summary

    Purpose: To verify that physicians’ presumptive diagnosis is the most significant factor for finding any signs related to the cause of fever on computed tomography (CT) images. Materials and methods: This single-center retrospective cohort study included patients (age ≥ 16 years) who underwent CT to investigate the cause of fever between January 1, 2014, and August 31, 2016. Patients who underwent surgical procedures were excluded. The primary outcome was the presence of suspicious CT findings related to the cause of fever. We performed univariate and multivariate logistic regression analyses, adjusted for CT contrast agent use, quick sequential organ failure assessment score > 1, and C-reactive protein level. Results: We enrolled 171 patients, of which 57 had CT findings, and 114 did not. Multivariate logistic regression analyses demonstrated a significant difference for the presence of a presumptive diagnosis by the attending physician (odds ratio, 4.99; 95% confidence interval 2.31–10.76; p < 0.01), but not for other covariates, including C-reactive protein. Conclusions: In hospitalized patients with fever, an attending physicians’ presumptive diagnosis is associated with the presence of fever-related CT findings. Improving the quality of the diagnostic assessment before the CT scan may lead to more appropriate CT imaging use.

     View Summary

    Sarcoidosis is a multisystemic granulomatous disease. It is rarely isolated in the spleen. The present report describes a case of isolated splenic sarcoidosis that was diagnosed histologically following laparoscopic splenectomy. A 76-year-old woman, who underwent radical nephroureterectomy 7 years earlier for left renal pelvic cancer and mastectomy 6 years earlier for left breast cancer in another facility, was referred to our hospital for assessment of splenic tumors that were identified during a follow-up examination. The computed tomography scans revealed multiple nodules in the spleen, which had increased in size over 2 years. Positron emission tomography revealed accumulation of [18F]-fluorodeoxyglucose in the spleen. Laparoscopic splenectomy was performed and the diagnosis of sarcoidosis was confirmed histologically. A review of previous reports and the present case suggested that diagnosis of splenic sarcoidosis should be considered when the CT scans show multinodular splenic tumors, and sarcoidosis might be associated with malignant tumors.

  • Applicability of ultrasonography for detection of marginal sinus placenta previa

     View Summary

    ABSTRACT: This study aimed to examine whether marginal sinus placenta previa, defined as when the marginal sinus just reaches the internal cervical os and placental parenchyma might be >2 cm from the internal cervical os, can be diagnosed using ultrasonography (US). We identified the placenta previa cases that underwent both US and magnetic resonance imaging (MRI) between April 2010 and December 2018 at our institution. The diagnostic discrepancies for marginal sinus placenta previa between US and MRI were examined retrospectively. Of the 183 cases of placenta previa, 28 (15.3%) cases were diagnosed as marginal sinus placenta previa using MRI. Among them, 18 cases (64.3%) could also be diagnosed using US. The sensitivity and specificity of the diagnosis of marginal sinus placenta previa using US were 64.3% and 92.9%, respectively. A change in US diagnosis occurred in 10 (35.7%) cases, all of which were diagnosed with low-lying placenta previa or marginal placenta previa and did not develop any serious miserable obstetrical outcomes. In conclusion, the diagnostic accuracy of US for detecting marginal sinus placenta previa was not significant. MRI examination may be required to accurately categorize the types of placenta previa.

  • T1rho magnetic resonance imaging value as a potential marker to assess the severity of liver fibrosis: A pilot study

    Suyama, Y., Tomita, K., Soga, S., Kuwamura, H., Murakami, W., Hokari, R. and Shinmoto, H.

     View Summary

    Purpose: Assessment of liver fibrosis is essential for the management of liver disease. Although liver biopsy is the gold-standard modality for the diagnosis of liver fibrosis, it has some limitations. Thus, other methods are required to overcome the disadvantages of a liver biopsy. T1rho magnetic resonance imaging (MRI) values are potential biomarkers for liver cirrhosis. This study aimed to assess the relationship between T1rho MRI values and liver fibrosis severity by measuring the correlation between T1rho values and shear wave elastography (SWE) values, which are routinely used for the diagnosis of liver fibrosis. Methods: T1rho imaging and SWE values were obtained from four healthy volunteers and 16 patients with chronic liver disease. The regions of interest on MR images were drawn and matched with those of the right liver lobe on SWE images. Results: The mean T1rho values of the right liver lobe correlated positively with the mean SWE values (Pearson's correlation coefficient: 0.783; p<0.0001; 95 % confidence interval: 0.623-0.880). Conclusion: The mean T1rho values of the right liver lobe may be correlated with the severity of liver fibrosis.
