We illustrate imaging findings in various imaging modalities including mammography, ultrasonography (US), magnetic resonance imaging (MRI) and positron emission tomography (PET) as well as review literature concerning this uncommon condition.</p> Sineenart Panichyawat Palita Hansakul Copyright (c) 2022 The ASEAN Journal of Radiology 2022-08-31 2022-08-31 23 2 90 115 10.46475/aseanjr.v23i2.135 Regression of lung bullae after pulmonary infection: Two case reports and the aspect of radiologic and pathologic findings in one case <p>A sharply demarcated area of emphysema, <em>bleb </em>or<em> bulla</em>, is usually asymptomatic. Some could lead to pneumothorax or superimposed infection, the common complications, while some could be spontaneously resolved, of which mechanism remains unclear.</p> <p>We present two male patients who had asymptomatic bullae at their right upper lungs. The first patient presented with a low-grade fever for a month. His chest radiograph showed a new patchy opacity in right upper lung, which corresponds to an enhancing mass with central necrosis on the chest computed tomography. His tissue pathology from two specimens of pleura had proven as inflammation and fibrosis. After antibiotics treatment, the follow-up images showed partial regression of the bullae. Another patient presented with right pleuritic chest pain for 16 days and was diagnosed as pneumonia with an infected lung bulla. His chest radiograph showed a newly seen patchy opacity at the right middle lung zone and a new air-fluid level in the lung bulla in the right upper lobe. After he had been given antibiotics treatment, partial regression of the bulla was observed. He later underwent right upper lobectomy and successful smoking cessation. The follow-up chest images showed no new bleb or bulla.</p> Tanaporn Eiambanapong Tanapol Jiwanan Pachayree Booncharoen Kanet Kanjanapradit Copyright (c) 2022 The ASEAN Journal of Radiology 2022-08-31 2022-08-31 23 2 116 129 10.46475/aseanjr.v23i2.169 Many good reasons to attend The 21st Asian Oceanian Congress of Radiology (AOCR) in Bangkok, Thailand <p>Challenges and opportunities are inevitably embedded to a crisis depending on which perspective we look at. During a couple of years of drowning in the COVID-19 pandemic, some existing concepts, means, work flows and tools failed to respond timely and effectively. Governments, industries, private sectors, and non-profit organizations have exerted all their efforts and resources to sustain the citizens’ livelihood by ensuring the smallest rate of morbidities and mortalities of the people to their full potential. New products and innovations were introduced and accepted at an unprecedented speed. Apparently, imaging, and related informative technological systems, serving as an important part in health industries, plays an indispensable role in triaging, diagnosing and caring for the COVID-19 patients.</p> <p>While the COVID-19 pandemic is still on-going, new knowledge and experiences are increasingly obtained. It is time to talk and share on the issue. The 21st AOCR in Bangkok, Thailand will provide the best opportunity in a friendly atmosphere for scientists, technologists and radiologists to share what they have acquired, what we should adopt and how we can adapt to improve our facilities in caring not only for COVID-19 patients but also patients inflicted with other diseases that threaten the health of people and burden the countries in Asia-Oceania.</p> Wiwatana Tanomkiat Jarturon Tantivatana Theerapol Panyaping Napapong Pongnapang Alongkorn Kiatdilokrat Dittapong Songsaeng Pittaya Dankulchai Copyright (c) 2022 The ASEAN Journal of Radiology 2022-08-31 2022-08-31 23 2 130 136 10.46475/aseanjr.v23i2.183 Correlation between shear wave elastography and vibration-controlled transient elastography of liver stiffness in chronic hepatitis B infection in Samut Sakhon Hospital <p><strong>Background: </strong>Assessment of the liver stiffness to evaluate liver fibrosis in viral hepatitis has been an important factor in the management guideline. Due to limitations of liver biopsy, non-invasive assessments of liver stiffness become a more practical method. Vibration-controlled transient elastography (VCTE) has been widely used for a long time and the newcomer, 2D shear wave elastography (2D-SWE) was claimed to possess a strong correlation.</p> <p><strong>Objective</strong>: To assess agreement and correlation of liver stiffness measurement using VCTE and 2D-SWE in patients with viral hepatitis B.</p> <p><strong>Materials and Methods</strong>: 34 patients with a laboratory confirmation as viral hepatitis infected were included. Liver stiffness measurements were obtained using 2D-SWE with VCTE serving as the reference standard on the same occasion. The differences of two measurements were demonstrated by both Bland-Altman and scattered plot. We analyzed their mean differences, 95% limit of agreement, and Spearman correlation (r<sub>s</sub>) coefficient to determine the agreement and the correlation of the 2D-SWE compared to VCTE.</p> <p><strong>Results: </strong>For VCTE and 2D-SWE, the median elasticity was 5.35 kPa (IQR 4.57, 6.77) and 6.90 kPa (IQR 6.07, 8.25), respectively. The mean differences of the elasticity of tissue between VCTE and SWE were 0.50 kPa (S.D. 3.25 kPa) and 95% limit of agreement was between -6.87 and 5.87 kPa. There was a strong correlation (r<sub>s</sub> =0.659) between VCTE and 2D-SWE.</p> <p><strong>Conclusion: </strong>In this pilot experience of these two methods, the initial correlation test in real clinical setting has proved a strong measurement correlation between Shear wave elastography and VCTE in hepatitis B patients. </p> <p> </p> Yasinee Mekavuthikul Lakkana Jirapong Orawan Autravisittikul Copyright (c) 2022 The ASEAN Journal of Radiology 2022-08-31 2022-08-31 23 2 73 88 10.46475/aseanjr.v23i2.151
