Consulting criteria for an imaging study may sound easy, but it requires a cultural change.
Transrectal ultrasound provides clear images of the prostatic anatomy and accurate guidance for prostate biopsy.1 The technique has become useful for the evaluation of patients with prostatic disease, but its success depends greatly on individual operators. It is important for radiology staff to understand the correct approach to prostate scanning and biopsy procedures, as well as the indications and limitations.
Mountaineering and climbing have been popular sports for many decades. The recent advent of artificial climbing walls and improved safety equipment have transformed the sport and brought it to a wider audience than ever. Such innovations allow individuals to climb safely in any weather conditions.
Coronary heart disease is one of the leading causes of morbidity and mortality in developed countries.1 Accurate detection of early cardiac disease is of utmost importance for the delivery of appropriate treatment.
Plaque rupture is the main cause of acute coronary syndromes, which are associated with high mortality and morbidity. The prevalence of plaque rupture in acute coronary syndrome is more than 70%.1 Rupture-prone plaques are characterized by a large core of extracellular lipid with a thin fibrous cap (Figure 1). Inflammation, particularly in the plaque shoulder, causes the fibrous cap to thin and results in disruption of the atherosclerotic plaque.
Although most hernias involving the anterior abdominal wall or groin can be diagnosed easily by inspection and palpation, imaging is the principal means of detecting internal, diaphragmatic, and other nonpalpable or unsuspected hernias.1,2
45-year-old woman with nonspecific pelvic pain and fullness, after MRI underwent cystoscopy and biopsy which revealed proliferative cystitis.
Radiation plays an important role in the treatmentof primary and secondary centralnervous system neoplasms.
A 47-year-old female with long stand history of hemodialysis and hypertension. No family history of breast cancer. No personal history of diabetes or smoking.
State-of-the-art units can show subtle changes to lung parenchyma that are not apparent on conventional radiographs or respiratory tests
A long-term study of breast imaging in Massachusetts has confirmed what mammographers have argued for years: older adult women who do not receive regular screening mammography are far more likely to die of breast cancer than women who routinely undergo the procedure.
As radiology practices continue to navigate the ICD-10 implementation, a look at how it can help the field.
Ablative techniques have greatly improved physicians' ability to definitively treat patients with primary and secondary hepatic tumors. These techniques include radiofrequency ablation (RFA) and cryoablation, as well as newer microwave and laser ablation methods. Ablation devices, used either alone or combined with hepatic resection, have made it feasible to treat patients with bilobar lesions and those who would not tolerate liver resection due to underlying comorbidities.
Advances in MRI modalities and capabilities can facilitate optimal comfort and help alleviate anxiety for patients.
Any fluid-filled cavity or sac that is lined by an epithelium is a cyst, and intracranial cystic lesions are a common finding on CT and MR imaging of the brain.1,2 These lesions contain either cerebrospinal fluid, fluid that is similar to CSF, mucus, or proteinaceous fluid. They are lined by epithelial cells, inflammatory cells, or glial cells. The attenuation characteristics of the cyst on CT and MRI and the contrast enhancement patterns depend on the cyst's contents and the composition of the wall.
Case History: 7-year-old male with left upper limb weakness that started two years following a motor vehicle accident.
Radiology benefit management companies are regulated and transparent in the criteria for determining medical necessity of testing, according to one exec responding to a recent article.
Case History: Patient presented with vision difficulty for one year, which increased in severity over last two months.
Case History: 51-year-old male, Blaschkoid eccrine spiradenoma originally manifested by cutaneous nodules, lesions experienced rapid growth two years ago.
Clinical History: A 42-year-old woman with no significant past medical history presented with three days of sharp left sided abdominal pain with associated nausea and anorexia.
A 20-year-old woman presented with a rectal mass that was malignant on biopsy. Chest radiograph and abdominal CT were ordered to look for metastases.
These four technology themes from RSNA 2013 will have far-reaching implications for radiologists in the next few years.
Case History: 30-year-old male with discomfort in left groin region due to mass/swelling for one year.
Case History: 47-year-old male with headaches followed by generalized tonic-clonic convulsions.
Bbone marrow edema is characterized by ill-defined areas of decreased signal intensity on T1-weighted MRI and increased signal intensity on T2-weighted images.
The feasibility of 3T MR as a general-purpose clinical imaging modality is an ongoing controversy. Although whole-body 3T MRI has been available for several years, most systems to date have been sold to university hospitals and research facilities.
Lack of reimbursement kept PET imaging on a slow track for most of the 1990s. The PET community's efforts to churn out data to persuade the government of the modality's effectiveness began to pay off early in the new century.
