Introduction Radiology residency programs demand high levels of proficiency in imaging interpretation, procedural skills, and clinical decision-making. Says Dr. Andrew Gomes, traditional training methods, which rely on didactic lectures, case reviews, and supervised practice, often face limitations in scalability, hands-on exposure, and real-time feedback. Virtual reality (VR) training platforms have emerged as an innovative solution, providing […]

Introduction Medical imaging plays a pivotal role in diagnosis and treatment planning, but ionizing radiation exposure remains an inherent risk in modalities such as CT, PET-CT, and fluoroscopy. Balancing image quality with patient safety is therefore a critical concern for radiologists and healthcare institutions. Says Dr. Andrew Gomes, radiation dose optimization strategies aim to minimize exposure […]

Introduction Picture Archiving and Communication Systems (PACS) have become an essential component of modern medical imaging, enabling the storage, retrieval, and management of diagnostic images. Says Dr. Andrew Gomes, traditional on-premises PACS solutions, however, face challenges related to scalability, maintenance, and remote accessibility. Cloud-based PACS systems offer a transformative alternative, providing secure, scalable, and flexible infrastructure […]

Introduction Hybrid imaging modalities, such as PET-MRI and SPECT-CT, represent a significant advancement in diagnostic medicine, combining functional and anatomical imaging into a single comprehensive examination. Says Dr. Andrew Gomes, while conventional imaging provides either structural or metabolic information, hybrid systems integrate both, enabling clinicians to assess disease processes with greater accuracy and precision. These technologies […]

Introduction Quantitative imaging biomarkers (QIBs) are measurable features extracted from medical images that provide objective information about tissue characteristics, disease progression, and treatment response. Says Dr. Andrew Gomes, unlike traditional qualitative assessments, QIBs offer reproducible metrics that can support personalized medicine and evidence-based clinical decision-making. However, the reliability of these biomarkers depends on standardization in acquisition, […]

Introduction Interventional radiology (IR) has transformed modern medicine by enabling minimally invasive procedures that reduce patient risk, shorten recovery times, and improve clinical outcomes. Says Dr. Andrew Gomes, traditional IR techniques, while highly effective, rely heavily on the skill and dexterity of the operator, which can affect precision in complex or delicate procedures. The integration of […]

Introduction Magnetic Resonance Imaging (MRI) has long been a cornerstone of non-invasive medical diagnostics, offering high-resolution anatomical images without ionizing radiation. While conventional MRI provides detailed structural information, it has limitations in characterizing tissue physiology, metabolism, and molecular processes. Says Dr. Andrew Gomes, advanced MRI techniques, including functional imaging and molecular characterization, have emerged to bridge […]

Introduction Medical imaging plays a central role in modern diagnostics, guiding clinical decisions across a wide range of specialties including radiology, cardiology, and oncology. Traditional image interpretation relies on the expertise of clinicians, which, despite being highly skilled, can be subject to variability and human error. Says Dr. Andrew Gomes, the advent of artificial intelligence […]
