TL;DR: FMRI reveals short-term physiological changes associated with active brain functioning, and in this way, fMRI can identify different parts of the brain where particular men-tal processes occur and can characterize the patterns of acti-vation associated with those processes.

TL;DR: The clinical and histopathologic feaures of PLCH, RB, RB-ILD, DIP, and AEP are discussed and their espective imaging appearances are illustrated, focusing primarily on highesolution computed tomography (HRCT).

TL;DR: Although MR imaging is excellent at delineating soft-tissue lesions, a correct histologic diagnosis based on imaging studies alone is seen in only 25%-30% of cases, and it is believed that this percentage continues to increase and ultimately will approach the 75%-90% range.

TL;DR: The radiologist must be sensitive to often subtle findings that may indicate that FAI is responsible or contributing to pain in young patients, and noncontrast imaging and, to a lesser extent, computed tomography have roles in the assessment of suspected FAI.

TL;DR: The development of advanced diagnostic MR imaging tools for the joints is of increased clinical importance as it has been recently shown that musculoskeletal imaging is the most rapidly growing field in MR imaging, second only to neuroradiology applications.

TL;DR: igh-resolution computed tomography (CT) is superior to hest radiography in the detection of ILD and is more accurate in he differential diagnosis and distinction of potentially reversible bnormalities from irreversible fibrosis.

TL;DR: Glenohumeral instability can be described as subluxation (partial loss of joint ongruity) or dislocation (a complete loss of contact between he articular surfaces of the humeral head and the glenoid ossa).

TL;DR: The imaging evaluation should be directed to detect surgically or percutaneously correctable processes, such as disk herniations, spinal stenosis, spondylolisthesis, vertebral compression fractures, or facet joint pathology.

TL;DR: An increasing number of organic and low-molecular weight compounds have been identified as causes of hypersensitivity pneumonitis, and the diseases caused by these substances are discussed.

TL;DR: An overview of the crucial anatomy and athology that is commonly encountered in the elbow joint long with examples of pathologic processes seen in routine ractice are presented.

TL;DR: The idiopathic interstitial pneumonias are a distinct group of clinicopathologic entities that play a critical role in the evaluation and management of patients and characteristic HRCT findings may be diagnostic, obviating the need for open lung biopsy.

TL;DR: The radiologists’ bility to best categorize a process as infectious with furher subdivision into categories, such as intra-axial, extraxial, congenital, or atypical can prove invaluable to the linician.

TL;DR: Imaging findings of the cortical and subcortical neurodegenerative diseases secondary to vascular insults are discussed.

TL;DR: The review will focus on the initial imaging iagnostic workup and will give a useful radiological aproach based on age, localization, imaging characteristics, and relative frequency of brain tumors.
