What does presence of artifacts mean?

Artifacts in electroencephalography (EEG) are defined as any electrical potential originating from a source other than the brain1. It is rare for an EEG tracing to be free of artifacts , with the reduction depending on the electroencephalographer’s accurate technique and the patient’s collaboration1,2.

What are artifacts in tomographic images?

In radiographic images , an artifact is an area with an optical density different from that expected, which was not caused by the interaction of the X-ray beam with the structure examined, but rather by some problem during the image acquisition, processing, handling or storage process. .

What is magnetic susceptibility artifacts?

Magnetic susceptibility artifact is commonly found in the presence of air, metal, calcium or concentrated gadolinium contrast medium, and appears as focal signal hypointensity surrounded by a hyperintense halo, which may be associated with distortion of the anatomy of the surrounding tissues.

What is the main cause of ring-like artifacts?

Among the causes are changes in the equipment, related to energetic parameters and factors related to the patient, causing artifacts with different characteristics/patterns ( ring- shaped ; movement artifacts ; generated by very dense materials; noise; dispersion and extinction ) (Schulze et al., …

What are the main reasons that generate artifacts in the image?

Main reasons that generate artifacts in images Finger marks caused by handling the film; Static electricity marks resulting from excessive flexing or unwrapped films; Air bubbles resulting from film processing; Stains and dirt.

What is partial volume effect?

The Partial Volume Effect (PVE) is one of the main factors responsible for image degradation in Nuclear Medicine. It is directly related to spatial resolution and image sampling, and results in an apparent decrease in the density of counts and an apparent increase in the size of structures.

What is FOV in MRI?

The field of view ( FOV ) represents the maximum size of the object under study that occupies the matrix, for example, a matrix can have 512 pixels in columns and 512 pixels in rows, and if the field of view is 12cm, each pixel will represent about 0.023cm (12cm/512).

What are the derivations?

Unipolar Leads are those in which only one electrode contributes to the electrocardiographic recording, the other electrode serves as neutral. Increased unipolar leads : there are three: aVR (right arm), aVL (left arm) and aVF (left leg). Precordial Derivations : these are derivations V1, V2, V3, V4, V5 and V6.

What is the U wave on the ECG?

The U wave is the last deflection of the electrocardiogram , representing the end of ventricular repolarization. Since Einthoven’s first description in 1903, until recently, his origin has been the subject of much discussion and the exact mechanisms involved in his genesis are still not entirely clear.

What does the QRS complex mean on ECG?

The QRS complex represents the activation of the ventricles. Next, the ventricles need to undergo an electrical change to prepare for the next heartbeat. This electrical activity is called a recovery wave, represented by the T wave. Many types of abnormalities can be seen on an ECG .

How to identify pathological Q wave?

To do this, we must evaluate the presence of a pathological Q wave in a given topography. The pathological Q wave must be at least 40ms long (1mm) and present at least 1/3 of the QRS amplitude, in 2 neighboring leads.

How does an ECG work?

The Electrocardiogram is also called ECG or electrocardiography. It is an exam that evaluates the electrical activity of the heart using electrodes fixed to the skin. Through this exam, it is possible to detect the heart rhythm and the number of beats per minute.

When does the ECG change?

An altered ECG report does not necessarily mean that the patient has a heart disease. Changes in the electrocardiogram may be due to a poorly performed examination, either due to a lack of adequate preparation of the patient’s skin during the examination, or due to the wrong position of the electrodes, or even serious illnesses.

How is the conventional ECG exam performed?

The 12-lead electrocardiogram is an exam performed in approximately 10 minutes and there is no need for preparation. Electrodes are placed on the chest and the electrocardiographic tracing is recorded.

How is the heart exam performed?

Que tipo de exame de sangue detecta infarto?

Atualmente, quando os pacientes se apresentam em salas de emergência com sintomas de ataque cardíaco, os médicos os avaliam em parte usando um teste de troponina cardíaca para medir uma proteína liberada no sangue quando o coração está danificado. Esse exame tradicional dura cerca de três horas.

Qual exame detecta miocardite?

O diagnóstico baseia-se no eletrocardiograma (ECG), em medições de biomarcadores cardíacos, exames de imagem do coração e biópsia do músculo cardíaco.

Qual o melhor exame para detectar arritmia cardíaca?

O eletrocardiograma (ECG) avalia a atividade elétrica do coração, o que permite verificar se os padrões encontrados são normais ou indicam alguma anomalia, como problemas no ritmo cardíacoArritmias, aumento de cavidades cardíacas e outras patologias coronarianas podem ser observadas no exame.

O que o holter pode diagnosticar?

Para avaliar a saúde do coração durante os exames de check-up pode ser solicitado o exame Holter, que consiste em um eletrocardiograma contínuo e portátil por 24 h. A finalidade deste exame é identificar distúrbios do ritmo cardíaco nas atividades diárias do paciente.

Como saber que tem arritmia cardíaca?

Os principais sintomas que podem indicar uma arritmia cardíaca são:

  1. Heart palpitation;
  2. Heart racing or slow;
  3. Chest pain;

  5. Feeling of lump in the throat;
  6. Tiredness;
  7. Feeling of weakness;
  8. Dizziness or fainting;

What can cause cardiac arrhythmia?

Stress: in excess, stress can make a person more likely to have arrhythmias such as atrial fibrillation. Chronic stress, generally caused by sleep apnea, high blood pressure and heart failure , can lead to arrhythmia and even sudden death.
