The chest radiograph (CXR) is the predominant imaging investigation being used to triage patients prior to either performing a SARS-CoV-2 polymerase chain reaction (PCR) test or a diagnostic CT scan, but there are limited studies that assess the diagnostic accuracy of CXRs in COVID-19.To determine the accuracy of CXR diagnosis of COVID-19 compared with PCR in patients presenting with a clinical suspicion of COVID-19.

The CXR reports of 569 consecutive patients with a clinical suspicion of COVID-19 were reviewed, blinded to the PCR result and classified into the following categories normal, indeterminate for COVID-19, classic/probable COVID-19, non-COVID-19 pathology, and not specified. Severity reporting and reporter expertise were documented. The subset of this cohort that had CXR and PCR within 3 days of each other were included for further analysis for diagnostic accuracy.

Classic/probable COVID-19 was reported in 29% (166/569) of the initial cohort. 67% (382/569) had PCR tests. 344 patients had CXR re was a 40% prevalence of PCR positive disease in the cohort of patients (n = 344) having CXR and PCR within 3 days of each other.Classic/probable COVID-19 was reported in 29% of total cohort of patients presenting with clinical suspicion of COVID-19 (n = 569).Initial CXR is useful as a triage tool with a sensitivity of 61% and specificity of 76% in the diagnosis of COVID-19 in a hospital setting.

The study aimed to describe the clinical and imaging course of reverse transcriptase polymerase chain reaction) confirmed coronavirus disease (COVID-19) patients who are asymptomatic at admission.

This was a retrospective observational study. Severe acute respiratory syndrome coronavisrus-2 (SARS-CoV-2) positive cases that were asymptomatic at admission were retrospectively enrolled. Specific clinical information, laboratory test results, chest CT imaging features and outcome data during hospital stay were collected and analyzed.

137 non-consecutive asymptomatic patients with reverse transcriptase polymerase chain reaction confirmed COVID-19 were enrolled in the present study. On admission, patients had no symptoms but chest CT findings were present in 61/137 (44.5%). Ground glass opacity (48, 78.7%) followed by ground glass opacity with crazy-paving pattern (9, 14.7%) were the commonest type of opacities with posterior, peripheral predominance and lower zone predilection. Among the initial CT positive ion (partial or complete), progression or no change.

Clinicoradiological course of asymptomatic COVID-19 cases is diverse.

Foetal MRI is used to assess abnormalities after ultrasonography. Bowel anomalies are a significant cause of neonatal morbidity, however there are little data concerning its normal appearance on antenatal MRI. This study aims to investigate the pattern of meconium accumulation throughout gestation using its hyperintense appearance on



weighted scans and add to the current published data.

This was a retrospective cohort study in a tertiary referral clinical MRI centre. Foetal body MRI scans of varying gestational ages were obtained dating between October 2011 and March 2018. The bowel was visualised on



weighted images. The length of the meconium and the width of the meconium at the rectum, sigmoid colon, splenic flexure and hepatic flexure was measured. Presence or absence of meconium in the small bowel was noted. Inter- and intrarater reliability was assessed.

181 foetal body scans were reviewed. GSK-LSD1 cell line 52 were excluded and 129 analysed. Visualisation of the meconium in the large bowel became increasingly proximal with later gestations, and small bowel visualisation was greater at earlier gestations. There was statistically significant strong (

= 0.6-0.8) or very strong (

= 0.8-1.0) positive correlation of length and width with increasing gestation. Interrater reliability was moderate to excellent (

= 0.4-1.0).

This study provides new information regarding the pattern of meconium accumulation throughout gestation. With care, the results can be used in clinical practice to aid diagnosis of bowel pathology.

The findings of this study provide further information concerning the normal accumulation of foetal meconium on MR imaging, an area where current research is limited.

Diagnostic radiology, being a computer-based service, is unsurprisingly at the forefront of the discussion of the use of AI in medicine. There are however differing schools of thought regarding its use; namely, will AI eventually replace the radiologist? Or indeed will it ever be fully capable of replacing radiology as a speciality, but rather be used as an aid to the profession whereby a human's input will always be required? Furthermore, what will the legal implications of AI in radiology mean to the profession? Who will be liable for missed diagnoses? Is it possible that the introduction of AI to radiology will in fact make the profession busier?The COVID-19 coronavirus pandemic has critically struck the world economy and healthcare systems. The highly contagious virus spreads rapidly and can result in potentially life-threatening acute respiratory distress. The current established test for diagnosing COVID-19 is using the RT-PCR laboratory test. However, the test requires specialized laboratories and testing kits. Recent reports also showed high false-negative rates. Experts recognize the urgent need to develop a rapid point of care diagnostic tests. Ultrasonography is a widely established safe diagnostic imaging test for detecting various lung abnormalities. Recent publications from China and Italy provided limited evidence on its usefulness for diagnosing COVID-19 in emergency departments earlier than RT-PCR. Ultrasound is sensitive to pleural and subpleural abnormalities, which suggests a great potential diagnostic role given the predilection for COVID-19 in peripheral subpleural regions.This paper reviews the current evidence and discusses the problems with specificity and scoring.
