1
hello everyone this is dr sam and today we will  study breast ultrasound image appearances here we
2
have the images of normal breast the uppermost  layer is the skin this is the hyperechoic
3
layer and below that is the subcutaneous zone it  is usually hypoechoic as compared to the tissues
4
below and the largest region is the mammary  zone it usually has mixed echogenicity most
5
of the pathologies occur in this zone and this  hyperechoic area is the fibro glandular tissue
6
these hyperechoic slanted or diagonal lines  are cooper ligaments this striated structure
7
is the pectoral muscle the retro memory zone lies  between the pectoral muscle and the memory zone
8
usually it appears smaller because it  is compressed due to probe pressure
9
and this shadowing over here is due to the  rib here we have more images of normal breast
10
we can see the three zones and the fibro  glandular tissue which is hyperechoic usually the
11
retro memory zone is below this fibroglandular  tissue but it is not always the case
12
breast pathologies can be classified  by using a system known as bi-rads
13
it stands for breast imaging reporting and  data system in total it has seven categories
14
in bi-rads 0 we need further images we need more  scans such as mammograms or ultrasound scans
15
bi-rads 1 is for normal breast tissue  where there is no mass or no distortion
16
no lesion both these images are by reds one
17
a simple cyst will appear as an anechoic structure  with posterior enhancement the cyst will be round
18
or ovoid with a smooth hyperechoic border it  is classified as bi-rads 2 which is benign
19
a complicated cyst will have fat  fluid levels and internal echoes
20
these are fat fluid levels the low density  fluid is at the top and the high density fat
21
is at the bottom now these cysts may  resemble malignant lesions that is why a follow-up is needed examples of complicated  cysts include oil cysts and galactocysts
22
a fibroadenoma is a benign tumor which will  appear as a hypoechoic round or ovoid mass
23
it may have a hyperechoic rim known as a pseudo  capsule and it has a parallel orientation it is
24
wider than tall you can see it is wider instead  of being taller this is a sign of benign lesion
25
it is classified as bi-rads 2 which is benign  however routine screening mammography should be
26
done here we have another image of fibroadenoma  it has a smooth border it may have calcifications
27
you can see the pseudo capsule here and it has  a parallel orientation it is wider than tall
28
a lipoma will appear as a hyperechoic rounded mass  usually hyperechoic rounded masses are benign it
29
has a bi-rads score of two despite this appearance  routine screening mammography should be done
30
hyperechoic masses that are ovoid rounded or well  circumscribed are usually benign another benign
31
feature is the parallel orientation in which it  is wider than tall examples include angio lipoma
32
hemangioma hamartoma they usually appear as  hyperechoic masses with a hyperechoic border
33
here we have an image of intra memory lymph  node they have a hypoechoic outer cortex
34
this is the cortex and a  hyperechoic central mediastinum
35
which is hyperechoic usually due to  fat they are classified as bi-rads 2
36
a neurofibroma is a rare benign tumor
37
which appears as a hypoechoic mass with posterior  enhancement now it is very tricky because it resembles a cyst so it can be misdiagnosed  very easily but it is a rare lesion
38
a sebaceous cyst is a complex cyst  which is present closer to the skin
39
here you can see it is present just below the  skin and it is even involving the skin so this superficial location can help us in diagnosing  sebaceous cyst it is classified as bi-rads 2
40
a simple cyst containing a  small hyperechoic calculus
41
is usually a milk of calcium  cyst these cysts are also benign
42
egg shell calcifications are small calcifications  which may have shadowing if they are a bit dense
43
they have a bi-rads score of  two complex cysts are rated as bi-rads 3 because they need a follow-up  exam usually thin hyperechoic septations
44
are benign but they still need a follow-up  so that is why it is rated as bi-rads 3
45
clustered microcysts will have a group of cysts  clustered together the diameter is less than three millimeters and septations may be present it is  rated as bi-rads 3 because follow-up is required
46
fat necrosis has a variety of appearances  in the acute phase the lesion is new so it may appear as a hyperechoic  lesion due to edema fat necrosis
47
appearances overlap with malignant lesions so a  follow-up is required so it is rated as bi-rads 3
48
fat necrosis enters late stage after 1.5 years
49
it will have calcified walls which  give posterior acoustic shadowing
50
now we move on to bi-rads categories which have  chance of malignancy bi-rads 4 has 3 sub-categories
51
in 4a the chance of malignancy is between 2 to 10  percent b is 10 to 49 and 4c is 50 to 94 percent
52
bi-rads 5 has greater than 95  percent chance of malignancy
53
and bi-rads 6 is a biopsy proven malignancy  usually hypoechoic masses with irregular walls or a speculated appearance are malignant  and they have a taller than wide orientation
54
here we have a case of lymph node metastasis
55
we are comparing it with a non-malignant  lymph node the cortex is very thick
56
which gives it an abnormally hyperechoic  appearance it is usually a sign of malignancy
57
intraductal papilloma is not very common its  appearance usually involves dilated ducts
58
and a well-defined nodule it is rated  as bi-rads 4 and biopsy is advised
59
intracystic papillary carcinoma consists of  a complex cyst with a thick mural based nodule
60
this nodule will be attached to  the wall it will not move around
61
here we have another image of intra-cystic  papillary carcinoma this one has a thick isoechoic septation as well these thick isoechoic septations  are usually a sign of malignancy as opposed to the
62
thin hyperechoic septation which is usually  benign and here is a large thick mural nodule
63
ductal carcinoma in situ will have hypoechoic  masses which will be micro lobulated which means they have these type of outpouchings and there  is no enhancement which means it is a solid mass
64
in this image the mass involves  the ducts so it appears elongated
65
usually these hypoechoic masses involving  the duct are ductal carcinoma in situ
66
invasive ductal carcinoma is the most common form  of breast cancer it also has variable appearances
67
one of them is a circumscribed mass
68
hypoechoic mass with some calcifications  which are usually invasive ductal carcinoma
69
here we have another case  of invasive ductal carcinoma
70
we have an ill-defined hypoechoic mass and it has  a non-parallel orientation it is taller than wide
71
the ap diameter will be more than the horizontal  measurement it also has posterior shadowing which is usually a sign of grade 1 invasive  ductal carcinoma but it is not always the case
72
here we have invasive ductal carcinoma  with posterior acoustic enhancement
73
this enhancement is usually a  sign of a higher grade cancer
74
it also has a speculated appearance suggesting  a malignant lesion it is rated as bi-rads 4c
75
here we have another image  of invasive ductal carcinoma
76
showing us a circumscribed hyperechoic  mass with uniform internal echoes
77
it also has posterior enhancement suggesting  a high grade cancer you can see that invasive ductal carcinoma has lots of appearances  ultimately it is confirmed with biopsy
78
mastitis is the inflammation of breast tissue its  appearances consists of hyperechoic fat lobules
79
and some hypoechoic areas another distinguishing  feature is that it has thickened skin here you can see the skin is very thick as compared to the  normal image these are the features of mastitis
80
duct ectasia involves dilated duct with  branching tubular anechoic structures
81
with the diameter measuring  more than two millimeters
82
the normal ducts are somewhat difficult to  visualize they usually have mixed echoes
83
here we have a case of infected and  inflamed cyst has thick isoechoic walls
84
and it has dependent debris which means  this debris will settle down due to gravity
85
this is the gravity dependent side this debris  will move in accordance with the patient position
86
this debris will move using this feature we  can differentiate it from a neural nodule
87
another feature is seen on doppler it is the  presence of increased blood flow in the thick wall
88
a normal breast implant is anechoic  with a double layered hyperechoic shell
89
and these are the normal breast tissues in  an implant rupture we have a step ladder sign
90
which are linear horizontal hyperechoic  bands representing force of a collapsed shell
91
it suggests intracapsular rupture
92
a silicone granuloma suggests extra  capsular rupture and gives us a snowstorm sign in this we have a hyperechoic  circumscribed superficial border
93
with dirty posterior shadowing  this shadowing is grayish
94

Praxis Tipps

Um das shadowing zu üben, hören Sie sich den Transkriptabschnitt in einem langsamen Tempo an. Wiederholen Sie die wichtigen Begriffe laut nach, um Ihre Englische Aussprache zu verbessern. Achten Sie auf die Intonation und den Rhythmus des Sprechens, um die Sprachmelodie des Englischen besser zu verstehen. Versuchen Sie, den gleichen Tonfall und die gleiche Betonung zu verwenden wie im Video, um effektiver mit Ihrem shadowing site zu üben. Halten Sie an bestimmten Stellen an, um mit eigenen Worten zu erklären, was gesagt wurde, oder um die Begriffe kreativ in eigenen Sätzen zu verwenden. Diese Methode hilft Ihnen, das Gelernte zu vertiefen und fließend zu sprechen, während Sie Englisch lernen mit YouTube. Verwenden Sie als zusätzliches Hilfsmittel auch visuelle Unterstützung durch die Bilder im Video, um sich die Konzepte besser einzuprägen und zu verankern.

Was ist die Shadowing-Technik?

Shadowing ist eine wissenschaftlich fundierte Sprachlerntechnik, die ursprünglich für die professionelle Dolmetscherausbildung entwickelt und durch den Polyglotten Dr. Alexander Arguelles populär gemacht wurde. Die Methode ist einfach aber wirkungsvoll: Du hörst englisches Audio von Muttersprachlern und wiederholst es sofort laut — wie ein Schatten, der dem Sprecher mit nur 1–2 Sekunden Verzögerung folgt. Anders als passives Hören oder Grammatikübungen zwingt Shadowing dein Gehirn und deine Mundmuskulatur, gleichzeitig echte Sprachmuster zu verarbeiten und zu reproduzieren. Studien zeigen, dass es Aussprachegenauigkeit, Intonation, Rhythmus, verbundene Sprache, Hörverständnis und Sprechflüssigkeit signifikant verbessert — was es zu einer der effektivsten Methoden für die IELTS Speaking-Vorbereitung und reale englische Kommunikation macht.
