What Is a PET Scan?

A Positron Emission Tomography (PET) scan is an advanced imaging technique used to observe metabolic processes in the body. By detecting radioactive tracers, PET scans help doctors diagnose diseases like cancer, heart conditions, and neurological disorders.

How Does a PET Scan Work?

The PET scan works by injecting a small amount of a radioactive substance (like FDG) into the body. This tracer emits positrons, which interact with electrons in the body, creating gamma rays captured by the scanner to create detailed images of organs and tissues.

What Is FDG in a PET Scan?

Fluorodeoxyglucose (FDG) is the most commonly used radioactive tracer in PET scans. It mimics glucose and highlights areas with high metabolic activity, often indicating the presence of tumors or inflammation.

The PET Scan Procedure: Step-by-Step Guide

• Consultation: Discuss your medical history and symptoms with your doctor.
• Preparation: Follow fasting guidelines and avoid certain medications.
• Tracer Injection: FDG is injected into your bloodstream.
• Waiting Period: Allow the tracer to circulate (typically 30-60 minutes).
• Scanning: Lie still as the scanner captures images.
• Completion: Results are interpreted by a radiologist.

Preparation for a PET Scan

• Fast for at least 6 hours before the scan.
• Avoid strenuous exercise 24 hours prior.
• Inform your doctor about any medications or allergies.

What to Expect During a PET Scan

You’ll lie on a table that slides into the PET scanner. The procedure is painless, but staying still is crucial for clear images.

After the PET Scan: Results and Recovery

• Drink plenty of water to flush the tracer from your system.
• Resume normal activities unless instructed otherwise.
• Results are usually available within a few days.

Difference Between PET Scan, CT Scan, and MRI Scan

Feature	PET Scan	CT Scan	MRI Scan
Imaging Type	Metabolic	Structural	Soft tissues
Radiation	Yes	Yes	No
Tracer Usage	Yes (Radioactive)	No	No
Time Required	30-60 min	5-10 min	30-60 min

What Is a PET-CT Scan?

A PET-CT scan combines metabolic imaging from a PET scan with the structural detail of a CT scan, offering a more comprehensive diagnostic picture.

Applications of PET Scans in Medical Diagnosis

• Cancer detection and staging
• Assessing heart health
• Identifying neurological conditions like Alzheimer’s

Benefits and Risks of PET Scans

Benefits:

• Early disease detection
• Accurate treatment planning

Risks:

• Exposure to low-level radiation
• Allergic reactions to the tracer (rare)

Cost of a PET Scan in India

PET scan costs vary based on the type and location but generally range between ₹15,000 and ₹25,000.

Choosing the Right Diagnostic Center for PET Scans

Look for:

• Certified radiologists
• Modern equipment
• Patient-friendly services

ECG Explained: How This Simple Test Protects Your Heart Health

Electrocardiography (ECG or EKG) is a crucial diagnostic tool used in modern medicine to assess the electrical activity of the heart. This non-invasive, painless test provides valuable insights into the heart’s rhythm, structure, and overall health, helping detect various cardiac conditions early. Let’s take a deep dive into what ECG is, how it works, and why it’s so important.

(ECG Test Kya Hota Hai) What is an ECG Test? 

An ECG is a medical test that records the electrical signals in the heart. With each heartbeat, an electrical impulse (or wave) travels through the heart, causing it to contract and pump blood. The ECG captures these impulses and translates them into a visual representation, typically shown as a series of waves on graph paper or a digital screen.

How Does an ECG Work?

During an ECG procedure, small sensors called electrodes are attached to the skin on the chest, arms, and legs. These electrodes detect the electrical impulses produced by the heart and transmit them to the ECG machine, which records the data and creates a graphical representation. The typical waveforms observed in an ECG include:

• P wave: Represents the atrial contraction (depolarization).
• QRS complex: Depicts the ventricular contraction (depolarization).
• T wave: Reflects the heart’s recovery phase (repolarization).

Types of ECG Tests

• Resting ECG: Performed while the patient is lying down and relaxed.

• Stress ECG (Exercise ECG): Conducted while the patient exercises on a treadmill or stationary bike to monitor the heart’s response to physical activity.

• Holter Monitor: A portable ECG device worn for 24-48 hours to track heart activity over an extended period.

• Event Monitor: Used for intermittent recording when patients experience symptoms.

Why is an ECG Important?

An ECG is often the first step in diagnosing various heart conditions, including:

• Arrhythmias: Irregular heart rhythms.

• Coronary Artery Disease: Blockages in the heart’s blood supply.

• Heart Attacks: Evidence of damage to the heart muscle.

• Electrolyte Imbalances: Abnormal levels of minerals affecting heart function.

When Should You Get an ECG?

Doctors may recommend an ECG if you experience:

• Chest pain

• Shortness of breath

• Dizziness or fainting

• Palpitations

• Unexplained fatigue

How to Prepare for an ECG

Preparation for an ECG is simple:

• Wear loose, comfortable clothing.

• Avoid using lotions or oils on the skin, as they can interfere with electrode adhesion.

• Inform your doctor of any medications you are taking.

(ECG Report Kaise Dekhe) Interpreting ECG Results

ECG results are interpreted by a cardiologist or a trained medical professional. A normal ECG shows a consistent rhythm and typical wave patterns. Abnormal results may indicate heart disease, electrolyte imbalances, or other conditions requiring further investigation.

How to Interpret ECG Test Results

Interpreting ECG results requires understanding the different waveforms and intervals. A trained medical professional typically evaluates:

• Heart Rate: Normal resting heart rate ranges from 60 to 100 beats per minute.

• Rhythm: Regular or irregular pattern of the heartbeats.

• P wave: Consistency and shape of the atrial contraction signal.

• PR Interval: The time taken for the electrical impulse to travel from the atria to the ventricles (normal range: 0.12 to 0.20 seconds).

• QRS Complex: Duration and shape of the ventricular contraction signal (normal range: less than 0.12 seconds).

• ST Segment and T Wave: Signs of ischemia or other abnormalities.

ECG Test Normal Range

For most individuals, the normal ranges in an ECG test include:

• Heart Rate: 60-100 beats per minute

• PR Interval: 0.12-0.20 seconds

• QRS Duration: Less than 0.12 seconds

• QT Interval: 0.35-0.45 seconds (varies with heart rate)

Any deviation from these values may suggest an underlying heart condition that requires further evaluation.

An ECG is a vital, easy-to-perform diagnostic test that provides essential information about heart health. Whether done for routine checkups or in response to concerning symptoms, ECGs help detect potential heart problems early, allowing timely and effective treatment. If you experience any heart-related symptoms, consult your doctor about whether an ECG is right for you.
