Background: Although CBCT was introduced in dentistry, it has a specific role in rhinology for assessing uncomplicated maxillary sinusitis. CBCT offers valuable information on anatomy and pathology with a low irradiation dose. Methods: We performed a systematic search on PubMed on the use of CBCT in detecting maxillary sinus pathology and the relation between dental lesions and maxillary sinusitis. Results: Specific findings, such as mucosal thickening, retention cysts, or antroliths, have been found to be associated with dental problems. These alterations can be incidental findings during the management plan for patients with dental problems, but can also be the reason that prompts the patient to perform the imaging investigation. Conclusions: The literature on the topic is quite comprehensive and clarifies percentages and the correct use of CBCT. As a minimally invasive procedure, CBCT finds its utility in assessing patients with dental problems, as they are more prone to accepting this fast, pain-free, and non- claustrophobic method. There are several limitations, such as the not-so-large target area and the less-than-average, limited pictures. However, CBCT remains a valuable tool that can be used for patients with suspected sinus problems that require dental treatment to ensure there are no future sinus complications.
Liver pathology represents, nowadays, a major cause of mortality and morbidity worldwide. Since MRI helps in limited cases in the differential diagnosis of various pathologies concerning liver tumors, other modern diagnostic strategies should be prioritized. Besides various tumoral biomarkers, contrast-enhanced ultrasound (CEUS) plays a substantial role in differentiating various liver pathologies due to its availability and specificity. Various contrast-enhanced substances used for CEUS assist mainly in detecting focal liver lesions and differentiating their malignant character. This review focuses on the main indications and limits of this novel investigation, considering that patients presenting with various liver pathologies are more challenging. We highlighted in our review the similarities with the CT/MRI imaging methods in reference to the specificity and sensitivity of the method, in its potential ability to detect various liver tumors. Moreover, the contrast agents used by CEUS are eliminated throughout the lungs, showing no evidence of hepatotoxic, nephrotoxic, or cardiotoxic events. In conclusion, the accessibility and safety of the procedure and the absence of the use of ionizing radiation point out that CEUS could be a stand-alone technique in the diagnosis and evaluation of complex liver pathologies.
