“…It is interesting because bronchial flow may enhance dramatically during PE [68] and may be measured on ultrasound [69] and it can be seen on CEUS [70]. In our case of chronic infarct (Figure 14) there was little flow with diastolic reversal (Figure 14C), which is a wellknown finding upstream to occlusion [71], but it might also be part of the normal spectrum in the peripheral pulmonary branch. We believe that there is a need for well-constructed, large research regarding Doppler flow in embolic and other consolidations, carried out by experienced Doppler operators.…”

In recent years, lung ultrasound (LUS) has developed rapidly, and it is growing in popularity in various scenarios. It has become especially popular among clinicians. There are constant attempts to introduce it in new fields, with quite a strong resistance in the radiological community. In addition, knowledge regarding lung and LUS has been augmented by the recent COVID-19 pandemic. Unfortunately, this has led to many misconceptions. The aim of this review is to discuss lines, signs, and phenomena that can be seen in LUS in order to create a single, easily available compendium for radiologists and promote consistency in LUS nomenclature. Some simplified suggestions are presented.

“…A similar low velocity signal, with no flow in diastole, was seen on the left side in Patient 6, while the typical reverse flow pattern was seen on the right. Patient 13 was the only one to have diastolic forward flow in the MCA at the time brain stem death was confirmed clinically ( Transcranial pulsed Doppler ultrasoundfindings in brain stem death Transcranial pulsed Doppler ultrasound findings in brain stem death 20,21,22,23), there was evidence of clinical and EEG deterioration but reverse flow in diastole was never observed in the sonagrams obtained. These children showed evidence of persisting brain stem function, as did Patient 19, in whom reverse flow was observed in diastole (DFI > 0 8, V > 10 cm/s) which subsequently disappeared.…”

“…Upon cessation of brain perfusion, characteristic flow patterns can be detected which confirm the lack of perfusion of these arteries [3,8,21,30]. This test can be performed only if an examination prior to the appearance of the clinical signs of brain death confirms intact function of the cranial base arteries.…”

The majority of European countries have published recommendations for the diagnosis of brain death as a necessary prerequisite for organ donation. The concept of brain death as defining the death of the individual is accepted in all European countries; however, the guidelines for determining the total and irreversible loss of all brain functions differ somewhat in the various countries. While the clinical examination and documentation of the clinical signs of brain death are very uniform, there are significant differences in the guidelines for using technical confirmatory tests to corroborate the clinical signs. These range from rejecting all technical tests to accepting of multiple neurophysiological tests alone or in combination. The present study examined the similarities and differences in current concepts of brain death in the various European countries and their recommendations for the diagnosis of brain death. The diagnosis of brain death is based on a number of prerequisites, on the clinical diagnosis of deep coma, loss of all brainstem reflexes, and the demonstration of apnea. Neurophysiological tests are recommended by a number of national professional societies as confirmatory tests to confirm the clinical diagnosis of brain death and shorten otherwise necessary waiting periods of 6-12 h. Most brain death codes allow the use of electroencephalography, which must demonstrate electrocortical silence over a certain period. Evoked cerebral potentials can demonstrate the successive loss of activity of various afferent pathways and are accepted in some countries as a confirmatory test. Other neurophysiological tests which demonstrate the loss of cerebral perfusion can be implemented. Brain scintigraphy can confirm the loss of isotope uptake into the brain. Doppler sonography also demonstrates cessation of brain perfusion. Cerebral panangiography may also be used to demonstrate the loss of brain perfusion but is less desirable since it might endanger the patient.
