In this study, third-harmonic generation (THG) imaging measurements were performed to characterize different developmental stages of the nematode Caenorhabditis elegans (C. elegans) embryos. Femtosecond laser pulses (1028 nm) were utilized for excitation. THG image contrast modality proved as a powerful diagnostic tool, providing valuable information and offering new insights into the complex d...

Thoracic venous aneurysms are a rare clinical entity and contrast-enhanced computed tomography has been the cornerstone of their diagnosis. We are reporting a rare case of isolated left brachiocephalic vein aneurysm, which was surgically managed, highlighting the role of dynamic contrast-enhanced magnetic resonance imaging as a definitive diagnostic modality in this patient.

Adverse drug reactions are a common problem for patients and their physicians. About 6% to 10% of adverse drug reactions are allergic. Obtaining a detailed history is very important. Discontinuation of therapy with a suspect drug is the most helpful diagnostic modality. It is also the treatment of choice. Consultation with an allergist for individualized evaluation and recommendations may be be...

Although it is standard of care for patient safety monitoring in anesthesia, capnography is not routinely used for emergency department procedural sedation and analgesia. We discuss the use of capnography as a diagnostic monitoring modality for procedural sedation and analgesia, focusing on the physiology and interpretation of the CO2 waveform and recognition of normal, abnormal, and drug-induc...

We report a 28 years old male presenting with heart failure. A thorough clinical evaluation directed us towards restrictive heart disease. Doppler echocardiographic study was used as a main modality of diagnosis and cardiac catheterization confirmed the diagnosis of idiopathic restrictive cardiomyopathy. We express the contribution of clinical findings and appropriate diagnostic measures in app...

Bronchiectasis is defined as abnormal, persistent bronchial dilatation, usually associated with inflammation in the bronchial tree and lung parenchyma. The disease remains a common cause of significant morbidity and mortality, especially when associated with COPD. Computed tomography (CT) is now the diagnostic modality of choice and may also contribute to clinical management. However, we would ...

CT is the preferred imaging modality to diagnose pulmonary embolism Evaluation of pulmonary embolism with dual energy CT (DECT) retains diagnostic accuracy using less contrast material than standard CT Virtual monochromatic images, derived from DECT data, show contrast material at greater intensity than standard CT Iodine images show the distribution of contrast material and can be used to asse...

Giant cell tumours of the spine above the sacrum are rare, and may pose diagnostic and treatment difficulties. A patient with thoracic vertebral giant cell tumour in which soft tissue extension and proximity to the spine complicated management is described. Magnetic resonance imaging is the imaging modality of choice for determining the extent of disease, assisting preoperative management, and ...

We present an unusual case of subjective right-sided pulsatile tinnitus that resolved spontaneously within a few weeks after diagnostic superselective angiography. The possibility of dural arteriovenous fistula should be kept in mind even in subjective tinnitus. Conventional angiography may be the only modality that shows the abnormality.

AIMS The aims of this study were to compare the diagnostic test characteristics of ultrasound alone, metal artefact reduction sequence MRI (MARS-MRI) alone, and ultrasound combined with MARS-MRI for identifying intra-operative pseudotumours in metal-on-metal hip resurfacing (MoMHR) patients undergoing revision surgery. METHODS This retrospective diagnostic accuracy study involved 39 patients ...
