SUMMARY: Interventional neuroradiology procedures are a valuable asset in the diagnosis, treatment, and surgical management of various disorders affecting the extracranial head and neck. A detailed understanding of cross-sectional and vascular anatomy and an awareness of potential collateral pathways between extracranial and intracranial vessels are essential for ensuring safe and successful procedures. With the use of high-quality imaging and a meticulous technique, the incidence of major complications is extremely low.

OBJECTIVE. Pulmonary tuberculosis (TB) is a common worldwide infection and a medical and social problem causing high mortality and morbidity, especially in developing countries. The traditional imaging concept of primary and reactivation TB has been recently challenged, and radiologic features depend on the level of host immunity rather than the elapsed time after the infection. We aimed to elaborate the new concept of the diagnosis and treatment of pulmonary TB, to review the characteristic imaging findings of various forms of pulmonary TB, and to assess the role of CT in the diagnosis and management of pulmonary TB.

CONCLUSIONS. Fast and more accurate TB testing such as bacterial DNA fingerprinting and whole-blood interferon-{gamma} assay has been developed. Miliary or disseminated primary pattern or atypical manifestations of pulmonary TB are common in patients with impaired immunity. CT plays an important role in the detection of TB in patients in whom the chest radiograph is normal or inconclusive, in the determination of disease activity, in the detection of complication, and in the management of TB by providing a roadmap for surgical treatment planning. PET scans using 18F-FDG or 11C-choline can sometimes help differentiate tuberculous granuloma from lung malignancy.

The temporomandibular joint (TMJ) is a small joint with complex anatomy and function. Diverse pathologies with very different symptoms can affect the TMJ.

While various imaging techniques such as plain-film radio - graphy and computed tomography can be useful, magnetic resonance imaging’s superior contrast resolution reveals additional structures like the articular disk, making this technique essential for accurate diagnosis and treatment planning.

We analyze the MRI signs of the different pathologies that can affect the TMJ from the structural and functional points of view.

The usefulness of PET/CT in lung cancer

Abstract
Lung cancer is the leading cause of cancer-related death. Accurate staging is essential for the optimal management and treatment of these patients.Positron emission tomography (PET) and,more recently, PET/CT have been introduced into the diagnostic algorithms for oncologic patients because they provide valuable functional information. The hybrid PET/ CT technique acquires both anatomic (CT) and metabolic (PET) images in asinglesession, combining the benefits of each modality and minimizing their limitations. This article reviews the role of PET/CT in lung cancer staging, with emphasis onnon-small cell carcinoma, evaluating the advantages and limitations of the technique. Other applications of the technique, such as planning radiotherapy, areal so discussed. KEYWORDS PET/CT; PET; CT; Lung cancer
