This chapter, found in the back pain section of the book, provides a succinct synopsis of a key study examining the use of follow-up magnetic resonance imaging (MRI) for patients with sciatica. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. Researchers concluded that the presence of disk herniation on MRI at 1-year follow-up after treatment for sciatica does not help distinguish between favorable and unfavorable clinical outcomes. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

This chapter, found in the back pain section of the book, provides a succinct synopsis of a key study examining incidental findings on magnetic resonance imaging (MRI) of the lumbar spine in patients without back pain. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. The study showed that many people without back pain have disk bulges or protrusions on imaging of the lumbar spine, but that these findings are frequently coincidental and should not necessarily lead to further tests or interventions. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

This chapter, found in the headache section of the book, provides a succinct synopsis of a key study examining the imaging selection and endovascular treatment for ischemic stroke. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. Researchers found that a favorable penumbral pattern by computed tomography or magnetic resonance imaging does not help identify patients who would benefit from endovascular therapy for acute stroke, and that embolectomy is not superior to standard care with regard to clinical and imaging outcomes for acute ischemic stroke. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

This chapter, found in the back pain section of the book, provides a succinct synopsis of a key study examining the use of magnetic resonance imaging (MRI) for low back pain. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. Researchers concluded that although spinal MRIs (compared with plain radiographs) are reassuring for patients with low back pain, they do not lead to improved functional outcomes; also, spinal MRIs detect anatomical abnormalities that would otherwise go undiscovered, possibly leading to spinal surgeries of uncertain value. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

This chapter, found in the back pain section of the book, provides a succinct synopsis of a key study examining the use of vertebroplasty for osteoporotic spinal fractures. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. For patients with pain from fractures of less than 1 year duration, vertebroplasty brings similar symptom and quality of life improvements as a simulated vertebroplasty. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

This chapter, found in the cancer screening and management section of the book, provides a succinct synopsis of a key study examining the efficacy of chest radiography for screening for lung cancer. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. Researchers reported that annual chest radiograph screening over a 4-year period did not decrease lung cancer mortality compared with usual care after 13 years of follow-up, and that chest x-rays are not an effective screening test for lung cancer. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

This chapter, found in the bone, joint, and extremity pain section of the book, provides a succinct synopsis of a key study examining the frequency of incidental findings on knee magnetic resonance imaging. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. Incidental meniscal damage on MRI was shown to be common in the general population, especially among the elderly, and is not necessarily attributable to patients’ knee symptoms. Authors advise those interpreting MRI reports and planning interventions that there is a high prevalence of incidental tears even among those without knee symptoms. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

This chapter, found in the chest pain section of the book, provides a succinct synopsis of a key study comparing the use of computed tomography angiography (CTA) and ventilation-perfusion (V-Q) scans for ruling out pulmonary embolism. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. The researchers report that a strategy to rule out pulmonary embolism and anticoagulation therapy using the methods in the study resulted in low, similar rates of venous thromboembolic events at 3 months follow-up; however, more patients were diagnosed with pulmonary embolism in the CTA arm of the study. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

This chapter, found in the back pain section of the book, provides a succinct synopsis of a key study validating the Canadian C-spine rule for imaging the cervical spine in alert and stable trauma patients. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. The study shows that the Canadian C-Spine Rule may be able to identify a large group of alert and stable adult trauma patients for whom cervical spine imaging is unnecessary. It may also help to standardize the appropriate use of cervical spine imaging in the emergency department. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

Objectives: We analyzed the magnetic resonance imaging (MRI) manifestations of fetal corpus callosum abnormalities and discussed their prognosis based on the results of postnatal follow up. Methods: One hundred fifty-five fetuses were diagnosed with corpus callosum abnormalities by MRI at our hospital from 2004 to 2019. Gesell Development Scales were used to evaluate the prognosis of corpus callosum abnormalities after birth. Results: Corpus callosum abnormalities were diagnosed in 149 fetuses from singleton pregnancies, and 6 pairs of twins, 1 in each pair is a corpus callosum abnormality. Twenty-seven cases (27/155) were lost to follow up, whereas 128 cases (128/155) were followed up. Of these, 101 cases were induced for labor, whereas 27 cases were born naturally. Among the 27 cases of corpus callosum abnormality after birth, 22 cases were from singleton pregnancies (22/27). Moreover, 1 twin from each of 5 pairs of twins (5/27) demonstrated corpus callosum abnormalities. The average Gesell Development Scale score was 87.1 in 19 cases of agenesis of the corpus callosum and 74.9 in 3 cases of hypoplasia of the corpus callosum. Among the 5 affected twins, 2 had severe neurodevelopmental delay, 2 had mild neurodevelopmental delay, and 1 was premature and died. Conclusion: The overall prognosis of agenesis of the corpus callosum is good in singleton pregnancies. Hypoplasia of the corpus callosum is often observed with other abnormalities, and the development quotient of hypoplasia of the corpus callosum is lower compared with agenesis of the corpus callosum. Corpus callosum abnormalities may occur in one twin, in whom the risk may be increased.
