Exploring Segmentation and Adaptive Attention in Deep Learning Models for COVID-19 CXR Diagnosis

Fatin Nabilah Shaari, Aimi Salihah Abdul Nasir, Wan Azani Mustafa, Wan Aireene Wan Ahmed

Background: Chest X-ray (CXR) image classification remains a critical tool in COVID-19 and pneumonia diagnosis. While segmentation of lung fields is commonly assumed to improve deep learning classification performance, recent evidence suggests that segmentation may also remove clinically relevant contextual cues. Attention …

CDPC-MRF: Contourlet-Based Density Peaks Clustering With Markov Random Field Refinement for Lung Segmentation

Ooi Wei Herng, Aimi Salihah Abdul Nasir, Abdul Syafiq Abdull Sukor, Wan Aireene Wan Ahmed

Accurate lung segmentation in chest X-ray (CXR) images remains challenging because rib interference, low contrast and disease opacity can weaken lung boundary separability, especially in pneumonia and COVID-19 cases. Although supervised deep learning methods achieve high segmentation accuracy, these models require annotated …

Hybrid Attention-Based CNN-BiLSTM Network for Aiding Covid-19 Diagnosis

Fatin Nabilah Shaari, Aimi Salihah Abdul Nasir, Wan Aireene Wan Ahmed

Accurate interpretation of chest X-ray (CXR) is vital for early detection of diseases like pneumonia and COVID19. Though CNN perform well in medical image classification, they often miss subtle spatial features due to limited receptive fields and uniform region processing. To overcome …

Could a handheld point-of-care ultrasound system alter the management of patients with pleural infection?

Wan Aireene Wan Ahmed, Mohd Jazman Che Rahim, Mohamed Faisal Abdul Hamid

Lung ultrasonography is an essential tool in the management of pleural infection. We report the usage of lung point-of-care ultrasound (POCUS) using a handheld ultrasound system (HHUS), which changed the immediate management of a complex pleural effusion. A middle-aged diabetic patient presented …

Oesophageal Foreign Body : A Toddler with Recurrent Stridor

Ca Wei Ng, Wan Aireene Wan Ahmed, Ahmad Aizuddin Mohamad Jamali, Choon Keit Chern

Stridor is not an uncommon complaint among the paediatric population presented to the Emergency Department. It is the cardinal sign of impending total airway obstruction. One of the obstructions can be due to a foreign body (FB) lodged in the airway. We …

Case of Culture-negative Infective Endocarditis With Atypical Presentation and Disseminated Multiorgan Embolism

Zul Khairul Azwadi Ismail, Wan Aireene Wan Ahmed, Ahmad Aizuddin Mohamad Jamali, Mohd Khairi Othman et autres

Infective endocarditis (IE) is associated with high morbidity and a mortality rate of 9-30% due to its life-threatening complications including systemic embolization of various organs. The complications are more common in culture-positive cases. In culture-negative IE, systemic embolism especially with multiorgan involvement …
