DHA Magnetic Resonance Imaging Technologists - Exam Topics Sample Questions

Which mode of transmission is direct contact?

Correct Answer:
sneezing.
the question asks to identify which mode of transmission among the given options is considered direct contact. the provided answer options are: fomite, sneezing, food, and water. *p direct contact transmission occurs when there is physical contact between an infected person and a susceptible person, and the infectious agent is directly transferred through this contact. examples of direct contact include touching, kissing, sexual contact, or contact with oral secretions. *p sneezing is a form of direct transmission, particularly for respiratory infections like the flu or the common cold. when a person sneezes, they expel respiratory droplets containing infectious agents directly into the air. if these droplets come into contact with another person's mucous membranes (such as the eyes, nose, or mouth), the infection can spread directly from one person to another. *p on the other hand, the other options listed—fomite, food, and water—are examples of indirect modes of transmission. a fomite is any object or substance capable of carrying infectious organisms (such as clothes, utensils, and furniture) and potentially transferring them from one individual to another. food and water can also serve as vehicles for pathogens if they become contaminated and are then consumed by other individuals, leading to foodborne or waterborne illnesses. *p thus, among the options provided, sneezing is the correct answer as it represents a direct mode of transmission. the other options, fomite, food, and water, involve an intermediary object or substance, classifying them as indirect modes of transmission. this distinction is crucial in understanding how diseases spread and determining appropriate control and prevention strategies.

Which of the following is a technique used to generate a high signal from water using very short Trs?

Correct Answer:
drive.


the correct answer to the question, "which of the following is a technique used to generate a high signal from water using very short trs?" is drive.

drive stands for driven equilibrium. this technique is utilized in magnetic resonance imaging (mri) to enhance the signal from water-containing tissues. by restoring the longitudinal magnetization to equilibrium more quickly than would naturally occur, drive effectively increases the signal intensity from these tissues. it is particularly useful because it achieves this enhancement even when using very short repetition times (trs).

short trs in mri are generally associated with faster imaging sequences. however, they can often result in decreased signal intensity, making it difficult to visualize certain tissues clearly. drive addresses this limitation by applying a specific radiofrequency pulse that drives the longitudinal magnetization back to equilibrium immediately after the signal readout. this action speeds up the recovery of the longitudinal magnetization, thus allowing for the use of short trs without sacrificing the signal quality from water-rich tissues.

the use of the drive technique is especially important in scenarios where rapid imaging is necessary, such as in dynamic or functional studies, or when patient compliance is a challenge (e.g., pediatric imaging or conditions that cause difficulty in remaining still). by maintaining high signal quality even with shortened scan times, drive helps in producing clearer and more diagnostically useful images.

in summary, drive is an effective mri technique for enhancing the visibility of water-containing tissues by using driven equilibrium to boost the signal intensity, even when operating with very low trs. this makes it invaluable in clinical settings where speed and image clarity are paramount.
