Introduction

In the field of medicine, the goal of personalized medicine is to provide tailored treatment plans to individual patients based on their unique biological characteristics. This approach is becoming increasingly important as it enables physicians to optimize patient outcomes while minimizing the risk of adverse effects. One critical tool in personalized medicine is molecular imaging, which enables the visualization of specific biological processes at the molecular level. In this essay, we will explore the role of molecular imaging in personalized medicine. Molecular imaging is now widely used in the treatment of many diseases, with a particular emphasis on cancer care. It refers to the in vivo identification and quantification of key biomolecules and molecular events that underpin malignant conditions. This article discusses both established and emerging molecular imaging methods in oncology. Current molecular imaging techniques have benefits for both clinical cancer care and drug development.

Cancer is one of the most difficult issues in public health care, affecting millions of people worldwide and leading to high mortality rates. According to the World Health Organization, cancer incidence, prevalence, and mortality are expected to rise significantly due to population growth and ageing because cancer is positively correlated with patients' ages, even if it affects younger people. This emphasises the importance of promoting and advancing healthcare systems and strategies, as well as developing conventional therapy methods such as chemotherapy, radiation therapy, and surgery, to eliminate cancer cells, increase patient survival rates, and ensure sustainability, while also providing satisfactory global healthcare based on prevention, accurate diagnosis, and effective treatment with less multi-drug resistance, high selectivity, and less cytotoxicity [1-3].

Literature Review

What is molecular imaging?

Molecular imaging is a medical imaging technique that enables the visualization of molecular and cellular events in living organisms. It uses non-invasive methods to create images of specific biological processes at the molecular level. It involves the use of specialized probes or tracers that bind to specific biomolecules and emit signals that can be detected by imaging devices. The probes can be labeled with various types of radioisotopes, fluorescent dyes, or other contrast agents.

The role of molecular imaging in personalized medicine

Molecular imaging plays a crucial role in personalized medicine by enabling the detection and monitoring of specific molecular targets that are involved in disease development and progression. It allows physicians to identify the underlying biological processes that contribute to disease and to assess the effectiveness of treatment strategies. Here are some of the specific ways in which molecular imaging is used in personalized medicine [4,5].

Ultra sound

Ultrasound is a high-resolution structural imaging technique that is widely used in diagnostic clinical imaging. Ultrasound is a biological system approach and imaging technique that can be used as two highly efficient methods for thermal cancer therapy therapies (thermoablation and high-intensity frequency ultrasound treatment (HIFU) that produces hyperthermia or hypothermia). It can also be used in clinical trials for diagnosis because of its advantageous properties such as its safety due to no ionising irradiation, wide availability, portability, real-time imaging/acquisition time (min), high spatial resolution, external or internal application (endoscopy), low cost, high sensitivity, and ability to be combined with contrast agents to separate contrast and morphological imaging (with use of harmonics). These characteristics increase interest in the wide range of ultrasound applications and its role.

Discussion

Diagnosis and staging of diseases

Molecular imaging can be used to diagnose and stage various diseases, including cancer, cardiovascular diseases, and neurodegenerative disorders [6,7]. For example, in cancer diagnosis, molecular imaging can be used to identify the presence and location of specific biomarkers, such as tumor antigens or receptors. This information can be used to determine the type and stage of cancer and to guide treatment decisions.

Treatment planning and monitoring

Molecular imaging can also be used to plan and monitor treatment strategies. For example, it can be used to determine the expression levels of specific biomolecules, such as hormone receptors, which can affect the response to certain therapies. Molecular imaging can also be used to monitor treatment response in real-time, enabling physicians to modify treatment plans as necessary.

Targeted therapy

Molecular imaging can be used to guide targeted therapies that specifically target the molecular pathways that contribute to disease. For example, in cancer treatment, molecular imaging can be used to identify the expression levels of specific biomarkers, such as HER2/neu in breast cancer, which can be targeted with specific drugs, such as trastuzumab. This approach can improve treatment outcomes while minimizing the risk of adverse effects.

Drug development

Molecular imaging can be used to evaluate the efficacy and safety of new drugs in development. For example, it can be used to determine the pharmacokinetics of a drug, which refers to how the drug is absorbed, distributed, metabolized, and excreted by the body. This information can help to optimize the dosage and administration of the drug.

Technologies used in molecular imaging

Several technologies are used in molecular imaging, including positron emission tomography (PET), single-photon emission computed tomography (SPECT), magnetic resonance imaging (MRI), and optical imaging.

PET

PET is a molecular imaging technique that uses positron-emitting isotopes to label biomolecules of interest. When the isotopes decay, they emit positrons, which interact with electrons in surrounding tissues, producing gamma rays that can be detected by PET scanners. PET can be used to visualize various biological processes, such as metabolism, blood flow, and receptor expression.

SPECT

SPECT is a molecular imaging technique that uses gamma-emitting isotopes to label biomolecules of interest. When the isotopes decay, they emit gamma rays that can be detected by SPECT scanners. SPECT can be used to visualize various biological processes.

Conclusion

This imaging technique has been used in therapeutics and diagnostics by determining the presence and extent of molecular targets for a specific disease and confirming the effective administration of these drugs; it is used for the targeted delivery of drugs, including genetic material, which is on the rise. It is also used in blood pool enhancement, perfusion imaging, characterization of lesions, phase and metabolism, echocardiography, monitoring and quantifying arthritis, identifying the phase of this heterogeneous disease, and detecting sites of atherosclerosis pathogenesis before lesions occur by accumulating microbubbles in ECAM-rich sites.
