Acute dyspnea is one of the most common complaints in any emergency department. Physical examination and chest radiography have been insufficient to diagnose these patients accurately and quickly. We present a clinical case of a dyspneic patient presenting to the emergency department, who was promptly diagnosed with lobar pneumonia by point-of-care pulmonary ultrasonography. This permitted the rapid onset of adequate treatment. (...) Keywords: Dynamic air bronchogram; lung ultrasound; point-of-care ultrasound

Theoretical Concepts of Lung Ultrasound in the Diagnosis of Congestion

A hiatal hernia (HH) is characterized by the protrusion of the stomach or other abdominal viscera into the mediastinum. The mechanism of increased intra-abdominal pressure is typically associated with this condition. When there are additional contributing factors causing increased abdominal pressure, like ascites resulting from chronic liver disease, it can (...)

Hiatal Hernia-induced Dyspnea in a Patient with Ascites: Leveraging Point-of-care Ultrasound for Accurate Diagnosis

Although US of the lungs is increasingly used clinically, diagnostic radiologists are not routinely trained in its use and interpretation. Lung US is a highly sensitive and specific modality that aids in the evaluation of the lungs for many different abnormalities, including pneumonia, pleural effusion, pulmonary edema, and pneumothorax. This review provides an overview of lung US to equip the diagnostic radiologist with knowledge needed to interpret this increasingly used modality.

Lung Ultrasound: The Essentials

Ultrasonography is often the initial modality used to evaluate patients found to have abnormal liver function tests (LFTs) in the emergency department. While an assessment for biliary ductal dilatation and obstruction remains one of the main questions to answer, radiologists should also be aware of the ultrasonographic appearance of other conditions that can cause abnormal LFTs. This may be crucial for (...) Keywords: Ultrasonography; Emergency; Liver function tests; Radiology; Diagnostic imaging

Ultrasonographic evaluation of patients with abnormal liver function tests in the emergency department

The resuscitation of a patient in shock is a highly complex endeavor that should go beyond normalizing mean arterial pressure and protocolized fluid loading. We propose a holistic, four-interface conceptual model of shock that we believe can benefit both clinicians at the bedside and researchers. The four circulatory interfaces whose uncoupling results in shock are as follows: the left ventricle to arterial, the arterial to capillary, the capillary to venular, and finally the (...)

Point of View: A Holistic Four-Interface Conceptual Model for Personalizing Shock Resuscitation

Over the past few years, social media has rapidly evolved into a major hub for medical education (#MedEd). Healthcare professionals across the globe increasingly turn to platforms such as X (formerly Twitter), Instagram, TikTok, Facebook, YouTube, and podcasts to access clinical information, follow scientific meetings, engage in professional dialogue, and even connect with the broader public. The rise of the Free Open Access Medical Education (#FOAMed) movement has further catalyzed this trend, particularly among trainees and (...) Keywords: ultrasound, POCUS, social media, cardiorenal

POCUS Over Punchlines: Rethinking the Cardiology-Nephrology Standoff in the Era of MedEd Humor

Key Points: Postoperative imaging is crucial for detecting and characterizing complications in the abdomen. / Many complications are common to all types of surgery, but some are specific to the type of operation performed. / Radiologists must use the type of operation, acuity of presentation, indication for surgery, timing relative to operation, and presence of comorbidities to help identify and characterize complications. / Radiologists must also be able to distinguish normal or expected postsurgical appearance from a complication.

Purpose: To provide an international expert consensus on technical aspects and clinical applications of quantitative lung ultrasound in adult, paediatric and neonatal intensive care. Methods: The European Society of Intensive Care (ESICM) and the European Society of Paediatric and Neonatal Intensive Care (ESPNIC) endorsed the project. We selected an international panel of 20 adult, paediatric and neonatal intensive care experts with clinical and research expertise in quantitative lung ultrasound, plus (...)

ESICM—ESPNIC international expert consensus on quantitative lung ultrasound in intensive care

Point-of-care ultrasound (POCUS) is a portable imaging tool used to guide clinicians in the rapid assessment of patients at the bedside. Because POCUS is noninvasive, radiation sparing, inexpensive, and allows for repeat examinations with evolving clinical circumstances, its use has increased. POCUS is commonly used in emergency departments (EDs) and intensive care units (ICUs), and is now part (...)

Point-of-Care Ultrasound in Sepsis and Septic Shock

Background - Current recommendations support guiding fluid resuscitation through the assessment of fluid responsiveness. Recently, the concept of fluid tolerance and the prevention of venous congestion (VC) have emerged as relevant aspects to be considered to avoid potentially deleterious side effects of fluid resuscitation. However, there is paucity of data on the relationship of fluid responsiveness and VC. This study aims (...)

Testicular ultrasound: an emergency medicine perspective

Cholecystectomy is one of the most common surgeries performed in the United States. Although complications are uncommon, the high incidence of this surgery means that a radiologist will likely encounter these complications in practice. Complications may arise in the immediate postoperative period or can be delayed for weeks, months, or years after surgery. Vague and nonspecific symptoms make (...)

Multimodality Imaging of Cholecystectomy Complications

Acute valvular emergencies, a time-sensitive diagnosis, are nearly impossible to diagnose without ultrasound, and missing the diagnosis can significantly impact patient outcomes. Many emergency physicians lack access to echo technicians and may be uncomfortable performing the ultrasound themselves. Approaching the paucity of review articles, none of which are focused for the emergency physician, can be quite daunting, even for those with extensive ultrasound training.

There has been a significant interest in venous congestion in recent years, among which the VExUS score has been prominent, both in clinical practice and research efforts. We have noted some recurrent misconceptions among clinicians which are also reflected in certain research efforts. Notably, the misguided attempt to correlate VExUS to volume status, which is only one of the factors influencing it, as well as attempts to re-interpret VExUS in the context of certain pathologies, which reflects a fundamental misunderstanding of its circulatory perspective.

Purpose of the Review This review article aims to show the actual role of Imaging, especially DECT (Dual Energy CT), in recognition of renal calculi. Recent Findings CT and in particular DECT have some implications in renal stone disease; CT is considered the gold-standard in the diagnosis in case of acute fank pain caused by nephrolithiasis, better than ultrasound, that represent the first approach, in some specifc cases. DECT instead in these days, has increase a very particular role. Keywords Acute fank pain · DECT · Dual energy computed tomography · Renal imaging · Stone disease · Urolithiasis
