How AI Is Changing Medical Imaging to Improve Patient Care
That doctors can peer into the human body without making a single incision once seemed like a miraculous concept. But medical imaging in radiology has come a long way, and the latest artificial intelligence (AI)-driven techniques are going much further: exploiting the massive computing abilities of AI and machine learning to mine body scans for differences that even the human eye can miss. Imaging in medicine now involves sophisticated ways of analyzing every data point to distinguish disease from health and signal from noise. If the first few decades of radiology were about refining the resolution of the pictures taken of...

Editorial Commentary: Routine Preoperative Magnetic Resonance Imaging for Hip Arthroscopy Is Wasting Health Care Dollars and Delaying Surgical Intervention: Decision Making Should Be at the Discretion of the Health Care Provider Not Mandated by Health Care Insurers
Arthroscopy. 2022 Nov;38(11):3020-3022. doi: 10.1016/j.arthro.2022.04.009.ABSTRACTMaking an accurate preoperative diagnosis is critical to optimizing outcomes after hip arthroscopy. A detailed history, thorough physical examination, imaging studies, and diagnostic injections must all be considered in the decision-making process. In today's health care climate, it is imperative to obtain essential and indicated preoperative information while being mindful of health care dollars. Magnetic resonance imaging (MRI) of the hip has been shown to be a highly sensitive modality for hip and pelvis disorders. However, it is critical ...

FDG PET of the Brain in Pediatric Patients: Imaging Spectrum with MR Imaging Correlation Nuclear Medicine
Positron emission tomography (PET) of the brain is an important problem-solving tool in pediatric neuroimaging, neurology, and neurosurgery. Fluorine 18 fluorodeoxyglucose (FDG) PET or dual-modality PET and computed tomographic (CT) imaging (PET/CT), with magnetic resonance (MR) imaging correlation, can be used to evaluate childhood epilepsy and pediatric brain tumors, areas in which PET adds value in patient management. FDG PET has been widely used in pediatric temporal lobe epilepsy, most commonly manifesting as mesial temporal sclerosis, which demonstrates hypometabolism at interictal PET and hypermetabolism during seiz...

Diagnostic Accuracy of History, Physical Examination, Laboratory Tests, and Point ‐of‐care Ultrasound for Pediatric Acute Appendicitis in the Emergency Department: A Systematic Review and Meta‐analysis
ConclusionPresence of AA is more likely in patients with undifferentiated abdominal pain migrating to the RLQ or when cough/hop pain is present in the physical examination. Once AA is suspected, no single history, physical examination, laboratory finding, or score attained on PAS can eliminate the need for imaging studies. Operating characteristics of ED‐POCUS are similar to those reported for RUS in literature for diagnosis of AA. In ED patients suspected of AA, a positive ED‐POCUS is diagnostic and obviates the need for CT or MRI while negative ED‐POCUS is not enough to rule out AA.

Non invasive cardiac output monitoring
Conventionally, measurement of cardiac output was done invasively. Initially with dye dilution techniques and later by thermodilution techniques. Both needed pulmonary artery catheterization, which in turn was likely to cause morbidity if used for continuous monitoring. Almost all non-invasive cardiac imaging modalities like echocardiography, computed tomography, magnetic resonance imaging and nuclear imaging can measure cardiac output. But these are not suitable for bedside monitoring, though echocardiography may be used for intermittent bedside assessment. Assessment of cardiac output though desirable, was most often ti...

Validity of the McMurray Test for Meniscal Tear in Pediatric and Adolescent Patients
Conclusion: In a pediatric and adolescent population, the McMurray test was negative for 61% (23/38) of meniscal tears identified on MRI. Clinical Relevance: Although the test can be a useful tool as a part of a thorough evaluation, combining it with mechanical symptoms, patient history and imaging may be more helpful to diagnose a meniscus tear.

Pediatric Nodular Fasciitis in the Head and Neck Evaluation and Management
Conclusions and RelevanceAlthough an uncommon diagnosis, nodular fasciitis should be considered in the evaluation and treatment of head and neck soft-tissue masses in children. Preoperative imaging is nonspecific and variable. Pathological findings are necessary for diagnosis. Surgical excisional biopsy is curative, with no instances of recurrence in our series.

The Use of Rapid Sequence Magnetic Resonance Imaging of the Brain as a Screening Tool for the Detection of Gross Intracranial Pathology in Children Presenting to the Emergency Department With a Chief Complaint of Persistent or Recurrent Headaches
Conclusions Rapid sequence MRI is a radiation-free useful alternative to computer tomography of the brain, when used as a screening tool for children with persistent or recurrent headaches presenting to the emergency department. This rapid imaging modality was particularly useful in identifying children with sinus disease, and contributed significantly to patient/family satisfaction with the care they receive during the emergency department visit. Additionally, RS-MRI screening was successful in detecting a serious neurosurgical emergency in one child with a cerebellar mass causing increased intracranial pressure. Furt...

A Rare Cause of Upper Airway Obstruction: Isolated Demyelinating Brainstem Lesion
Abstract: Acute upper airway obstruction derived from any cause can be a life-threatening emergency in pediatric patients. The major causes are infection, foreign body aspiration, and trauma. However, acute neurological disorders occasionally may manifest as severe airway obstruction. In our case, we report a 10-year-old patient presenting with prominent upper airway obstruction requiring intubation and respiratory support. He also had fever, encephalopathy, and involvement of multiple cranial nerves. Cranial magnetic resonance imaging showed a hyperintense lesion covering all of the medulla oblongata on T2-weighted images...

Interventional magnetic resonance imaging as a diagnostic and therapeutic method in treating acute pediatric atlantoaxial rotatory subluxation.
Authors: Hannonen J, Perhomaa M, Salokorpi N, Serlo W, Sequeiros RB, Sinikumpu J Abstract Atlantoaxial rotatory subluxation or fixation (AARF) is a rare condition, usually occurring in pediatric patients. It mimics benign torticollis but may result in permanent disability or death. The condition requires prompt diagnosis by thorough examination to avoid any treatment delays. Spiral computed tomography (CT) with three-dimensional reconstruction CT is recommended for identifying incongruence between C1 and C2 vertebrae, and magnetic resonance imaging (MRI) may be performed to exclude ligamentous injuries. In addition...

Magnetic resonance imaging protocols in pediatric stroke
AbstractNeuroimaging protocols play an important role in the timely evaluation and treatment of pediatric stroke and its mimics. MRI protocols for stroke in the pediatric population should be guided by the clinical scenario and neurologic examination, with consideration of age, suspected infarct type and underlying risk factors. Acute stroke diagnosis and causes in pediatric age groups can differ significantly from those in adult populations, and delay in stroke diagnosis among children is a common problem. An awareness of pediatric stroke presentations and risk factors among pediatric emergency physicians, neurologists, p...
