magnetic resonance imaging — diagnosis Magnetic resonance imaging (MRI) is a powerful diagnostic technique that is used to visualize organs and structures inside the body without the need for X-rays or other radiation.

A blood smear is a critical diagnostic tool in medicine, serving as the gold standard for identifying malaria and evaluating various blood disorders.12

To perform this examination, a thin film of blood is spread onto a glass slide, treated with a special stain (such as Wright stain), and viewed under a microscope. This process allows for the following observations:32

Detection of Malaria: The diagnosis of malaria is established by directly observing Plasmodium parasites within the red blood cells. Microscopic analysis is essential for distinguishing between the different species of parasites that cause the disease.21
Analysis of Blood Cells: The smear allows for the inspection of individual red cells, white blood cells, and platelets. Physicians can identify abnormalities in the size, shape, and color of these cells. For example, in iron-deficiency anemia, red cells appear paler than normal due to a lack of hemoglobin, while changes in the proportions of specific white blood cells can indicate various infections.23
